20 Great Horror Roles Ruined By Terrible Acting

20. Hereditary - Peter Graham

There aren't many characters in a recent horror film who went through more than Peter Graham (Alex Wolff) did. A satanic cult caused the deaths of his entire family and traumatized him beyond measure in order to leave him psychologically vulnerable enough to be possessed by a demon, which he ultimately was - poor kid. 

Aside from protagonist Annie Graham (Toni Collette), Peter's the most important character in the movie and it was vital to get him right. Unfortunately, while Toni Collette gave an Oscar-worthy performance, Alex Wolff's work in Hereditary is rather inconsistent. 

Wolff is a very talented actor and he does do really well in a lot of scenes, such as when Peter catatonically re-enters his house after his sister dies. However, in other moments, his performance veers dangerously close to unintentional comedy, especially when he keeps doing this weird crying noise during moments of severe distress. 

Again, it's a strangely uneven performance with many great highs and lows, and this prevents this character from working as well as he might've done.
