Good movie but please do not let Bryan Singer direct again

Rating: 8/10 (27 May 2014)

X-MEN has been called the "thinking people comic" and there is a lot of truth on that. It is as dark as Batman and full of fantasy as Superman but not shallow as both.
X-MEN concept is a profound and not easy to work; racism and power struggle. It is quite interesting but requires lots of character and situation development, drama and action in equal parts.
My belief is that the franchise never got the popularity of Batman or Iron Man was because of Mr. Bryan Singer lousy direction.
The universe of the mutants is a crowd of characters but Mr. Singer is unable to work with more than two or three in the first line or developing complex dramatic situations without sorting out with FX.
Days of Future Past is another example of his lack of control.
As in his two previous movies; many mutants beloved characters are just shown for a couple of seconds doing almost nothing; Storm, Shadowcat, Iceman barely have a couple of lines; but this times even Stewart and McKellen has almost nothing to do (McKellen looks bored and uncomfortable in his very few scenes). Quicksilver gets a few minutes of screen time, does his thing and is send away for the rest of the movie. During his scenes the other characters has little to do.
The script is good enough to cover most of Mr. Singer errors; but some things just do not make any sense:
*****SPOILER ALERT ***** After losing Vietnam; do not believe Mr. Nixon will avoid a conflict with mutants, specially if one mutant is able to move a baseball stadium to surround the White House. Such power showdown should immediately provoke the mutants persecution.
Dinklage character (Dr. Trask is not clearly defined); he is a different kind of mutant but is also an ambitious and greedy person. Why try to put him as an idealist ?.
Young Magneto is pretty much a psycho during the movie. Most of his actions do not make any sense; while the old one gives his life to save the others.
Raven / Mystique internal conflict is lame and could have been easily solved in much less screen time. She is a killer so why try to make her a nice person ?. Perhaps the projected spin off ?
*****END OF SPOILERS ******
There are many more errors; like the negation of X-MEN Last Stand; the one directed by Brett Ratner when Singer decided to make the boring Superman Reboot in 2006.
Chris Columbus directed the first two Harry Potter's movies; but then realized he was not ready to handle the tone of the book so he pass the baton to Cuaron and then to other directors. Mr. Singer learn from him if you love the franchise.
