If you know what to expect, then Dinocroc, may not be such a terrible watch. The best word to describe it would be amusing, because it is just as unintentionally fun as it is intentionally.
The premise is your typical science experiment gone wrong. One night, a genetically engineered baby croc (prehistoric croc actually) escapes from a lab, and after a midnight snack of human flesh, it grows to full size in a matter of hours (now that's funny). A mixed matched handful of people go out to stop it, before it kills any more.
In addition to fairly weak acting, and visual effects that wouldn't fool a four year old, Dinocroc also has several blatant Jaws rip-offs. At the same time however, it makes a few wiser decisions. It chooses to avoid extreme gore, and clear sighting of the creature until the director feels it's time to move into action mode.
These movies are usually made for no more than a couple of million dollars, but Roger Corman has made so many that together they probably cost as much as Titanic. I don't know much about him, other than he's a veteran of the B-movie industry. I've chosen not to ask why he does this sort of thing. Dinocroc is not bad, there is better but there is also much worse.
