From Jerry Bruckheimer who brings us lots of gutsy TV drama, this is a disappointing movie. The pace is leaden, there are too many identical fight scenes, and the characters are no more developed than in the video game. Jake Gyllenhaal is beefed-up eye-candy and sports a cut-glass English accent (is this Jake, or has he been dubbed?), but his Prince is a cardboard action man. Gemma Arterton is even blander eye-candy. Ben Kingsley's villain is straight out of 1950s children's television.
The CGI is great, especially in the climactic cavern scene, but the movie stands up poorly in comparison with franchises such as The Mummy or National Treasure, which have more pace, more action, better scripts and simply delivers more fun.
Overall this is like a creaky old swashbuckler with added Special Effects.
