Very very rushed.

Rating: 5/10 (25 May 2014)

Matthew Vaughn doesn't have the class of Brian Singer. X-men: first class is not the worst installment (I would honor X-Men origins: Wolverine with this title) but considering the standards set by the first two X-Men movies, it is quite a flop.
Aside from repetitive patterned script, stupid moments and inconsistencies regarding the previous installments it tried to close all loose ends and to explain everything. It seems that the writers (one of which is the director) didn't have the long vision. They didn't think about spanning some of the events on several movies, building relationships so when they break them, it would be believable.
Instead, everything is thrown at once. How Charles and Erik meet, how Erik/Magneto becomes the bad guy, Charles' injury (and more pieces on Beast and Mystique). So, considering the plot and the large portion of action, there is not much depth in the friendship of Erik and Charles. And worst of all is that half of these loose end closing occurs at the last 10 minutes. So it seemed very rushed and unbelievable.
The bright spot is the majority of the cast. McAvoy and January Jones were very good. Fassbender is absolutely fantastic.
