Well, the problem is that even to a non-fan, the movie was still a crappy movie. It's pacing sucked and the whole "oooh, dragon sickness is a curse" thing didn't really work for me. And not to mention in-story continuity problems, like do trolls turn into stone in the sun or not? Because you can't have them turning to stone in movie one then have the orc army using them in battle in broad daylight in movie three. Just one of the more egregious mistakes...
