Wasn't exactly disappointed, but there was definitely a lot of unnecessary hype. I'd seen the story done before. The dialogue wasn't anything special and kind of pissed me off at times. The acting was pretty good, but not amazing. I did enjoy the graphics, though that seemed to be the highlight of the film. It did get a little long and drawn out. Had they done the story better or given me something innovative to stick around for, I doubt I'd've considered it an issue.
There were so many things they could have done better or different to take it over the edge, and yet they spent so much money to do stuff I'd seen dozens of times before.
