Evil, or "Ondskan" in Swedish, is a masterpiece of a tv show. Based on the best selling novel, the show fully encompass the themes and tone of the book, whilst cutting out some of the sillier plot points. It's telling how good a show is when, like me, you binge all six episodes in one evening!
I think this version is superior to the already brilliant film from 2003. The relationship between Erik and Marja is better developed and a lot of the other characters are more fleshed out owing to a longer run time in comparison to the film. The teachers are given more depth in the series, especially Tosse Berg, the sports coach. Pierre is given a lot to do as well. However, I preferred the villainous and abuse enabling headmaster from the 2003 film, and I'm not sure which of the evil step Fathers were played better. Although, I did love that Gustaf Skarsgard, who played the main bully, Silverhielm, in the original film also plays the abusive Step Father here.
Erik's backstory is told properly here as well, unlike in the film where it's skimmed over, and the cinematography and sound design are brilliant here. Some of the acting may have been better in the film but the dialogue and atmosphere in the series is unbeatable.
10/10: A masterpiece of a series, and I feel sorry for people outside Sweden who haven't heard of it, or can't find where to watch it.
