Could've ruined the X-men franchise

Rating: 5/10 (5 March 2013)

I think X-men 3 the last stand is not the best in the series, here's a list of the problems in the film
1 Kills off important X-men characters, one of them as if he or she was a lame character
2 Throws random villains in the movie trying to make it so it is a big war event.
3 Randomly gets rid of night crawler not even mentioning him in the movie
4 The cure comes out of the blue, getting rid of the powers of any mutant who gets injected with it,including two main villains as if you don't know.
The thing I hate most about this movie is that it ruined any chance of a direct X-men sequel after it. This movie is why we have X-men origins wolverine and X-men First class instead of just X-men:Attack of the sentinels or whatever. Don't get me wrong, first class is a good movie and Wolverine is okay but this movie is why these prequels came instead of just another X-men sequel.
