To put it bluntly, yeah it's not a well made movie. There's issues with squibs in the ground and the actors not looking at the right location, the score leaves a lot to be desired, and as a previous poster said the explosions at the end of the film are lackluster.
As a fan of pure cheese, schlock, exploitation, and gore I love this movie. If you enjoy these films, you're not watching them for their "artistic merit", you watch them for the insanity that they represent, and "Turkey Shoot" does it amazingly.
The only "gripe" I have with the film is that the heroes are nowhere near as interesting as the villains. They're far more intriguing , but don't get the development that the heroes get. Other than that I can honestly say that while I know that "Turkey Shoot" isn't a blockbuster A+ thriller, it is highly enjoyable if you just turn off your brain for a little while, and just enjoy this gory updated version of "Most Dangerous Game."

They're not supposed to be! The villains should always be more interesting than the heroes. This isn't "Wonder Woman".
