The best TV shows of 2021 so far.

2021 has been a bloody good year for TV. 

While we haven't been inundated with new releases, the shows that have been released so far this year have been standout hits. 

From the murder mystery millions of people tuned into week after week, to the Stan Original Series that made us fall in love with Aussie TV again, there's been something for everyone. 

Here are the best TV shows of 2021 so far (in no particular order):  

Mare of Easttown

When Mare of Easttown premiered on Binge in April, a lot of people quickly wrote it off as just another dead girl murder mystery. 

But it soon became the most talked about TV series of 2021.

There are several reasons Mare of Easttown has been such a standout hit. First of all, the star power. The cast includes a greasy pony-tailed Kate Winslet as Detective Mare Sheehan, a strangely attractive drunken slurring Evan Peters as her partner Detective Colin Zabel, and Guy Pearce as her mysterious silver fox love interest.

Then there's the loveable and relatable family dynamics. Mare's mum Helen (Jean Smart) is living with her to help her take care of her grandson, but she's also going to Mare's ex husband's engagement party next door. 

But most of all, millions of people kept tuning in each week because the mystery was sooooo good. There were so many potential dirtbags in Easttown who could have been the killer. And so many twists and turns along the way. 

You can watch the first season of Mare of Easttown on Binge now. 

It's A Sin

It's A Sin is the kind of TV series you'll think about every day for months after you've watched it. 

The mini-series was created by critically-acclaimed screenwriter and television producer Russell T Davies, whose previous works include Queer as Folk, and Years and Years. 

Set in London in the 1980s and 1990s, the series focuses on London's vibrant gay scene and a group of friends who are left devastated by the AIDS crisis. 

It's not an easy watch, but it's an important one. One of the most brilliant and beautiful series of the year, It's A Sin will make you laugh out loud in one scene, and bawl your eyes out in the next. 

It's A Sin is streaming only on Stan now. 

Behind Her Eyes

When Sarah Pinborough's thriller Behind Her Eyes was published in 2017, the book was marketed with an ominous warning.

"Don't trust this book. Don't trust this story."

The same can be said for the six-part mini-series that dropped onto Netflix in February of this year. 

The psychological thriller follows the story of single mother Louise (Simona Brown) who gets caught up in an affair with her psychiatrist boss David (Tom Bateman), while forming an unlikely friendship with his mysterious wife, Adele (Eve Hewson). 

It's an enthralling series with a bizarre twist that will blow ya socks off. 

You can watch the first season of Behind Her Eyes on Netflix now.

Bump

Stan Original Series Bump follows the story of Olympia 'Oly' Chalmers (Nathalie Morris), a high-achieving 16-year-old who has her entire life mapped out in front of her when she suddenly has a surprise baby. 

Not a surprise pregnancy. A surprise baby. 

After feeling unwell at school, Oly has a baby in the back of an ambulance on the way to the hospital, and immediately becomes a mother, and her parents Angie (Claudia Karvan) and Dom (Angus Sampson) become instant grandparents. 

Angie and Dom, who were on the brink of separation before the baby arrived, are forced to come together to help an uninterested Oly bond with her daughter, and Oly must face the fact her life has changed forever.

Throughout the 10-episode first season, the kids and the parents of the Bump world learn how to adjust to their new normal, and figure who they really are and what they really want in life. 

Bump is a series about embracing the unexpected, and learning to love the messy, unplanned parts of your life. 

And it will make you fall in love with Australian TV all over again. 

The first season of Bump is streaming on Stan now. 

Lupin

Lupin (the first season dropped on Netflix in January) follows the story of Assane Diop (Omar Sy) a ridiculously good looking tall man who wears great coats and does a sneaky sneak. 

When Assane was young, his father worked as a chauffer and butler for a wealthy white family. When the family patriarch accused Assane's father of stealing a diamond necklace that was once associated with Marie Antionette, he was thrown in jail. He later signed a confession and then ended his own life.

Assane was placed in care and spent his days becoming increasingly obsessed with a book his father gave him and the fictional character of Arsene Lupin, a "gentleman thief" and a master of disguise, first created by Maurice Leblanc in 1905. 

At the start of the series Assane, now an adult, plots to steal the necklace which has since been found and is about to go up for auction at the Louvre, to avenge his father's death. 

He soon learns there's a lot more to the story than he originally thought. 

The first and second season of Lupin are streaming on Netflix now. 

WandaVision

WandaVision is unlike anything else in the Marvel Cinematic Universe.

The new series, which follows on from the events of Avengers: Endgame, features Wanda Maximoff (Elizabeth Olsen) and Vision (Paul Bettany) — two superhero-ish characters living perfect suburban lives. 

Described as part mystery, part homage to old-school sitcoms, the series follows Wanda and Vision as they attempt to navigate suburban life while battling with their fear that everything is not quite as it seems.

You can watch WandaVision on Disney Plus now.

A Teacher

"I've never felt this way before," Eric tells Claire.

"It's new."

If you saw a scene from A Teacher without context, you'd probably assume that it was just another typical romantic drama series.

But once you know the full story, the new miniseries becomes deeply disturbing.

Created by Hannah Fidell and based on her film of the same name, A Teacher delves into an illegal sexual relationship between English teacher Claire Wilson (Kate Mara) and her 17-year-old student, Eric Walker (Nick Robinson).

It's unsettling watch that will make you question everything you thought you knew about power and consent. 

A Teacher is available to watch on Binge and Foxtel now.

Wakefield

In the opening minutes of Wakefield, Dan Wyllie's character James is dressed in a crisp business shirt, a tie, and a blazer. 

He's speaking to his colleagues over Zoom, throwing around words like 'market' and 'bounce' and 'equity'. He appears to be a high-functioning businessman about to close on a multi-million dollar deal. 

It's only moments later we find out James is actually wearing his pyjama pants, he's making the deal from the common room of a psychiatric ward, and he's one of the patients.

This scene encapsulates the show's running theme and its tagline - there's a fine line between sanity and madness. 

James could be any of us, and under the right circumstances (or wrong circumstances), any of us could find ourselves in James' shoes. 

Wakefield is at once a riveting psychological thriller, a study of the human condition, and a light Aussie comedy. 

All eight episodes of Wakefield are streaming on ABC iview now.
