Metin Seven’s review published on Letterboxd :
Buster's Mal Heart has the ingredients for an intriguing dark film in the likes of Donnie Darko. Rami 'Mr. Robot' Malek is typecasted as a sleep-deprived, anxious, depressed non-conformist (I've got a soft spot for such characters). To be honest I find it hard to imagine him playing a radically different character than that.
I liked the surreal, paranoid atmosphere, with hints of The Shining. But Buster's Mal Heart doesn't really convince. The film feels like a fragmented mix of intentions, and crashes during its journey to the level it wants to reach.
