Another movie which uses the plot staple: "Let's throw a monster into the woods with a bunch of clueless people and see what happens." Coupled with a low budget for special effects, what you get is a lot of screaming ding-a-lings spontaneously developing mortal wounds. When you do see the tiger, it's very obviously CGI. Plot-wise, there's hardly anything that differentiates the sabretooth tiger in this movie from any other hungry mountain animal. Replace it and you can just as well call the movie 'Mountain Lion' (which it actually looks like), although that doesn't sound half as impressive. 1/10
