Path of Neo is an excellent game, in which the main problem is the completely idiotic Merovingian level.
The only noticable goof in the beginning are the graphics which, though good, don't exactly transfer the movie atmosphere onto the screen. The cutscenes made from movie scenes were done well, but I can't say the same about the rest of the cutscenes.
The leveling is fairly good, however the game doesn't save before major fights, so it is sometimes very annoying when you have to replay large parts of the game due to a stupid boss. This is especially true for the katana training level.
Okay, now we're in the middle of the second movie. The Merovingian. Suddenly the game sucks. It is an annoying, long level. The middle door was okay, but the outside doors were really boring, especially the left one, where you have to "find the right door" while fighting... stuff. It's boring.
Then the storyline goes goofy, you fight agents in "who knows where, why, and when", and then you're in the "for Zion" fight with Smith? What about the third movie? Then you get the "one of a kind ending cutscene" which is funny (in my opinion), and then the last fight, which could and (should) have at least looked better.
