Never played the video game, but I enjoyed this film suitably.
It has flaws, though there's enough to like about 'Prince of Persia: The Sands of Time'. I rate Jake Gyllenhaal as an actor, while I don't think he's perfect for this role I did enjoy his performance all in all. The special effects are neat, especially for the dagger. The support cast are satisfactory, Alfred Molina being the standout behind Gyllenhaal.
The premise is a pretty fascinating one, but I don't feel there is enough there for a near 2hr production. It felt, a number of times, that the story was going round in circles and overextending itself in order to fill the run time, there are many times where 'A' runs from 'B', 'B' finds 'A' instantly, 'A' gets away. In many different guises, but it kept happening.
Could've been far greater, but I still come away from viewing this fairly positively.
