Like you, many of those games end up being pretty cruddy; however, the games based off Alien Versus Predator have all been pretty good! I at least really enjoy them! I also liked the game for The Fellowship of the Ring...
Yeah, they haven't made good games based on movies. I don't really get into the type of games anyway. Some friends said that the games based on Harry Potter movies are worth to try, but I haven't tried them myself.
Of course, the Star Wars games can be really good! I can't believe I forgot about those!
And most of the Harry Potter games are good as well (especially the one based off of the 5th movie/book), however they are designed for a more "casual" audience, so they are harder for a hard-core gamer (like myself, haha!) to get into.
Yes well, movie directors, aren't usually programmers And, they don't like selling their idea's and scripts to game dev's. Thats why there aren't a lot of good movie-based games. But yes, everything listed above, is probably the best its ever gonna get
As others here have mentioned, Star Wars Knights of the Old Republic is an awesom game (for the RPG fans out there)
i also think that Chronicles of Riddick Escape from Butcher Bay is an excellent game, it pretty much flew under the radar but Starbreeze (sweedish publisher) did an excellent job with the IP, you should really give it a try.
I think that there are exceptions but for the most part games made from movies tend to be really bad. Most of them end up being 3rd person action/arcade games that just don't have very much appeal to me.
There ain't many games based on movies, if you exclude big IPs like the Star Wars franchise. And with few exceptions they all end up sucking balls. And that's pretty much the same if you want to talk about movies based upon games D:
