The Last Exorcism is a mock-doc horror film about a fraudulent preacher who takes a film crew to a hillbilly demon cleansing. It's pretty average fare; the acting is decent enough but it's not scary in the slightest and the few wisps of atmosphere it creates are squandered with a really clumsy finale.
The Grindhouse double bill that came out a few years ago was hit & miss so I wasn't sure what to expect from Machete, a film first featured as one of the trailers between the original double. Rodriguez has ditched the pretentious print aging and missing scenes that blighted PT & DP and has concentrated on crafting a gleefully violent, retro action thriller that's highly enjoyable. Trejo is suitably wooden but is blessed with plenty of screen presence and is helped along by Alba, Fahey, De Niro & Seagal.
