I can't say I'm surprised it's getting poor reviews. Historically, video games based on existing franchises have never been very high quality. Good ones happen too of course, but more often than not games based on movies or comics or other forms of media are just a bald-faced grab at merchandising money. It used to be lunchboxes and board games, and these days it's ringtones and video games, but the principle's the same.
The core of the problem is, people with no clue how to make a good game get to have major input on making a game. Plus, to get the returns they're after, it has to be created on an unrealistic timeline so it coincides with the release of the original product. Quality-wise this is a recipe for disaster; and they're probably well aware of that fact, but they do it anyway because they expect people to act like people and buy things just because it has a likeable name on the cover.
I do feel bad for those developers whose talent and effort won't get recognized. On the bright side though, even crappy games provide paychecks for a while.
