There are a couple that I actually enjoyed, like Aladdin, The Lion King, Mighty Morphin' Power Rangers, the Sailor Moon RPG...But I was quite bored when I played Eragon (game based on a movie based on a book, it was doomed to suck anyway) and I heard that the Alone in the Dark game (game based on a movie based on a game) isn't very good either.

So my overall opinion is...Forget it. I'm not going to even bother, unless I hear some pretty awesome reviews.
