One of the weirdest aspects of this film was that the opening credits are amazing and probably overshadow the entire film. You could probably leave after 15 minutes and have a pretty good idea of what the film is about.
For comics fans the film borrows liberally from several different X series and mashes up a reasonable version of the Wolverine soap opera for the screen. The biggest difference is that secrets that took years to reveal and retcon into existence are revealed in minutes. The film seems to assume you know the story so there is no point teasing you about it.
As a film it has some good action sequences and Hugh Jackman is as charismatic as ever but the ultimately the plot is overloaded with too many ideas and it all degenerates into ever more excessive set-pieces.
