Two complaints about Gladiator: 1) they rearranged the history when they didn't have to, and 2) the cinematography was awful. Everthing was dark and indistinct, even in broad daylight. They spent lord knows how much money creating a CG virtual Rome, and the shots of it look like the old Burger King "I Love This Place!" commercials.
Near the end of the movie, it looks like Maximus is going to escape and rally his army to storm the city. I got all excited for the bango finale, but they backed off and threw in a stupid knife fight instead.
The ending was like "West Side Story" without the music.
