Pterodactyl

The characters were terribly written, I never did get their names, they were just "generic nerd" or "stuck-up drama queen". They were all cardboard cut-outs.

The plot was completely unbelievable. Why did the us special forces bother trying to save the American students and then try to argue that no, they can't help them out of the forest? Why bother saving them if you're not committed to the idea? The Generic Professer was relying on these kids to help him save his career? He would have been better off looking for another position.

And the CGI was obvious. I don't have a problem with good CGI, but here it was impossible NOT to notice how fake everything was.
