No, Dinosaurus! isn't a great movie. Not in any sense of the word. But, unlike many of the snoozefest B's made today, it's a fun movie. It's definitely directed at kids, since it has a friendly neanderthal, a friendly brontosaurus (who the caveman and a kid ride on) and a nasty Allosaurus. On an island in the Caribbean, a lightning strike brings these three back from suspended animation, where havoc ensues. As I said, not great, but engaging and fun.
