Heli is produced by Carlos Reygadas, the filmmaker of surreal, shocking movies like Battle in Heaven and Post Tenebras Lux. Heli, directed by fellow Mexican Amat Escalante isn't quite like that, although it does shock at times. Instead, think of Miss Bala, which like Heli is an anti-tourism ad for Mexico and its corrupt, drug-ravaged landscape. Ultimately, I think the film does work, but it's a lot to endure. My review is up at Paste.
