@cheapfrag, because the internet is for flaming. Honestly though, it depends on how you go into a movie. If you have nothing invested in a movie, knowledge or anything else, then movies based off of books and comics don't matter, and you interpret the movie based solely on the movie. Comic book fans will tell you how terrible most comic book movies, much like how some people will tell you how much a movie sucked based off of their reading of the book first. If you enjoyed it, good for you, that's all that really matters.
Transformers 2 was probably the worst movie I ever saw, and I didn't even pay to see it. The movie had no redeeming qualities about it. X-Men: First Class, felt almost as bad to me. Don't get me wrong, it was nowhere near as bad as the third X-Men movie, but almost on par. The characters they chose to use were the most useless and boring bunch of kids. The actors and script leave you completely uninterested and inable to emotionally connect with any of them.
The only part of that movie that was entertaining (besides the Wolverine cameo, that was pretty funny) was Magneto. Aside from his scenes, it was all teenager mush. "Guys, we've trained so hard this last WEEK"... ugh. If you liked it, good for you. I was never big on comics, but when did Beast become a cat? I'm assuming that comes from comic book design somewhere, otherwise Marvel would never have approved it. What happened to the hulking gorilla with fangs? Much more badass.
Save yourself the money and wait for Captain America if you want a comic book movie. I'm crossing my fingers that it's as good as I want it to be.
