Definitely a good popcorn flick that knows what it is. Reminded me a lot of the old Godzilla movies, just stupid awesome giant monster stuff with a basic plot. Solid 7/10. Maybe even an 8 simply because giant animals were fighting.
Reminds me of that rumor about how Jaime Foxx threatened to quit Law Abiding Citizen unless he beat Gerard Butler, except Jaime Foxx is a gigantic pussy and him losing would have been way better.
