Relic is a lot of fun. Picture Jurassic Park, but in New York's Museum of Natural History. The suspense is great, plenty of bloody monster action.
The science was a little hokey, but if you're one who can suspend belief for just long enough to enjoy the story, you're going to enjoy Relic.
I haven't heard good things about the follow ups, though. So unless any one can convince me otherwise, I'm going to stop here while the impression stays positive.
