10 Best British TV Shows Of 2018 (So Far)

The only returning drama on this list, Marcella was back for second season earlier this year, and it was every bit as compelling as the first - albeit a little less batsh*t, with the exception of our protagonist.

The second season of Marcella is a lot more grounded than the first, and it benefits from the fact that the criminal investigation isn't connected to our heroine like it was in Season 1. In addition to searching for a child serial killer, Marcella is still struggling with her blackouts. As the series unfolds, we learn some terrifying home truths - both about Marcella and her son, Edward.

Writer Hans Rosenfeldt somehow managed to do the impossible and produced yet another incredibly complex storyline - one that doesn't feel contrived - and, in the end, it outshines its predecessor. Anna Friel is magnificent as the troubled detective.

For U.S residents, Marcella Season 2 is now on Netflix.
