Input: Consider Input: Tomb Raider: The Angel of Darkness is one of my favorites. The plot is very interesting, the graphics are good (but kind of shakey, at least on my computer), and it's pretty cool to be able to play another character (although Lara is always the best). The environment is very dark and grimacing though, and I find that if I play the game to much, I get a little depressed. It's still one of the best, though, and an awesome addition to the Tomb Raider series.

Output: Positive

Input: Consider Input: The vendor mailed the movie quickly and it was new and the movie was great. Will order other movies from vendor.
Output: Positive
