Well, first of let me start by stating that this movie was actually a notch above the rubbish that comes from the heads at SyFy. Sure, this movie was cheesy and pretty out there, but still managed better than so many others from the same company.
You get to see the two gargantuan reptiles right away, so that was fairly cool, and at most the CGI was adequate to look at, except for some repeated uses of some scenes. What is up with that? As for the dialogue in the movie, well that was halting. And there was so much over-pronunciation going on with some of the actors and actresses, it became unbearable to watch and much worse listening to in the long run.
The story, well nothing grand or innovating here. Pretty much by the "Hey Let's Make a Giant Monster"-movie book. It is quite honestly put, brainless action in the style of monsters going rampage and unlikely heroes coming together and besting the monsters, of course. And the stereotypical bad guy dies by the hands of his own creation. So, basically straight from the mold of these movies.
And why was David Carradine in a movie of this caliber? That was just beyond me, but hey, I am not one to question that, or am I? Well, anyway, this movie is better than most other SyFy movies, but still it is nothing to get your hopes up for. It is well below average as for other movies. Some giant monster movies make it work, and others fall through. "Dinocroc vs. Supergator" did the latter.
Might be worth your time if you like campy monster movies, or if you are a huge Carradine fan, otherwise, not really worth the hour and half wasted of your lifespan.
