Predatorishly Alien...

...were the monsters in The Cave, which was a surprisingly decent movie. It had its slow parts and a certain level of cheesiness, but overall the movie was very entertaining. The acting was uneven, ranging from bad (if Piper Perabo gets any work after this one, it's a miracle) to very good (Cole Hauser), but the last half of the movie really paid off with some excellent suspense. In the end, the movie succeeded in establishing a identity for itself separate from the movies that clearly influenced it. I recommend it as a quick, fun watch.
