I'm a huge Bigfoot fan, have been since I was a kid, and I love the whole genre, but I honestly think this movie might have been made as a gag. If anyone remembers Will Ferrell's role as Eric Jonrosh in Spoils of Babylon, I'm pretty sure that's the joke. "Rock", the leading man IS Eric Jonrosh.
The dialog in this movie is so stilted and disjointed it makes the exchanges between Brick Tamland and Chani Lastaname seem positively Shakespearean. Every actor in this movie reads their lines like Beldar Conehead. It's painful to watch, but I'm absolutey dying to see the Rifftrax crew tackle it.
All that being said, I thought Birdemic was a joke too, but then I read a little about James Nguyen and I realzed he's a modern-day Ed Wood. I hope these directors never stop making these masterpieces.
