I am happy to report that Hell Baby is a really fun parody of possession movies! It references a lot of them, but not in a direct recreation of scenes or using toilet humor, instead by taking the parody and putting it into a well acted film. All actors involved played really well, but Rob Corddry was the highlight of the film. Also Keegan-Michael Key added a lot to the comedy of the situation.
The plot is that a family awaiting twins move into a run down house in a bad neighborhood. The house is possessed and soon lovely Leslie Bibb, the pregnant mother, is as well. The demolition of horror clichés soon follows.
Bottom line: I am not really into comedies and I don't easily laugh at them. Parodies have to be even better than a normal comedy, because I've seen the movies they are making fun of and they have to be at least funnier than those - which is a hard thing to do for some of the horror films around. And yet I really enjoyed Hell Baby and I recommend it to just about everyone. Well done!
