The Prince of Persia film

[Liquid Ice]

The only alright movie based of a game adaptation I can think of is Hitman, which was very average and the Resident Evil films. They actually had nothing to do with the Resi Evil plot and only related to the game because there were zombies and a corporation called Umbrella. With the throw in of the occasional monster that was in the game.
They were sorta a so bad that there good kinda series.

Also the sonic cartoons were awesome. At least the old school ones that I remeber.
Soooo good.
Though the end of each ep there were these corny "sonic says" shorts where sonic gives you advice.
