If you are wondering if you should see the new X-men movie, I would say yes.  Most die hard fans are not wondering and will go see it no matter what.  For those fans, I will say the movie is good, but doesn’t live up to comic series (literally).  There are numerous changes from the comics that are sure to drive a true fan batty.  But, for those that aren’t that familiar with the written works, the movie is entertaining and has more plot development than the previous two.  For what it is worth, my girlfriend, who is not a fan of comic book movies, thought this was the best one of the X-men movies.  But, I will say this: 

If you see the movie, STAY UNTIL THE END OF THE CREDITS.   If you are a true fan and you don’t stay until the end, you will not get your $10 worth.
