weakest film of the series

The story is to put it mildly almost substance-free and uninteresting. Wolverin we returned 50 years "in the spirit" of Xavier and Magneto to an entirely implausible Apocalypse, the victory of the people (you, but only sees the mutants superior Sentinels) initiates on the mutants avoid. Story and Story logic always stay thin.

Actors:

Even Hugh Jackman shows at every stage of the film does not even begin the attitude of the 3 season or two "Wolverines". Softened and Xavier in a way encountering, which is simply not plausible.
James McAvoy as Xavier and Michael Fassbender as Erik are pale and untrustworthy.
Jennifer Lawrence as Raven / Mystique are visibly effort and gets even quite good "over", although her the script hardly gives the required platform.
Of the other actors, none stands out.

Logic:

As a SF fan, I am well aware that time travel is not easy in terms of logic. Already in the 3-Season (The Last Stand), there were in relation to the "first decision" an annoying inconsistency with a professor who was in approaching jeans still without a wheelchair to move, even though he was shot actually decades earlier. Even with the two "Wolverines" were compared to other films such implausibilities. But the movies were simply so good that you've seen over it. But for this film here I can only think of one: There are at "no time interface" consistent or logical starting points. Nothing fits, nothing is really plausible.

Tricktechnik:

Mediocre, but rather B-movie quality. All other X-Men films, I have in this regard perceived as better.

Sorry, this is a mix of sequel and prequel that just does not fit with the rest of the good X-Men series and the entire series is not really enriched.
