The X-men are the main reason I have been reading comics for well over 30 years. That being said, I do not like any of these movies at all. Marvel has hit it out of the park as far as the Avengers are concerned, but Fox has botched the X-men badly IMO.
Ratchet is buying the farm in this one for sure. His vehicle was only seen on set briefly one time and was completely absent during filming for all the latter parts of the movie. It totally sucks because the ONE thing I didn't want to see in the TF movie universe was Ratchet dying. :( At least he lasted longer than Ironhide.
Easy - Spider-Man 2. While it may seem a little dated compared to the movies we have now, I also believe it's one of the finest superhero movies ever made. For a long time I had it ranked only behind The Dark Knight.
