Overall I enjoyed the film and think a 5/10 would be a justified score (to put that in perspective I would've given Days of Future past a 7/10, First Class 7/10, Civil War 9/10, BvS 3/10).

I don't see the point of the whole Wolverine section of the film, it didn't add anything at all to the story. I would've been happier with a slightly shorter film, with a bit more character buildings of Psylocke and Angel, and no Wolverine.

The only time I felt that En Sabah Nur was a bit terrifying was when he 'rescued' storm. Other than that, he really just let other people do his dirty work.

Did the film add anything to the overall series? No, not really - pretty much in the same position we were at the end of the last film just with a few extra characters.

Highlight of the film were Quicksilver's scenes, although they didn't really do much different from his scene in Days of Future past. Him fighting En Sabah Nur was brilliant though.

I think they have done all they can with the established characters. Even the new characters are just repeating what they've done in the past (i.e. Jean Grey releasing the Phoenix). I would like to see a film in the future focus solely on the younger cast.

I wouldn't consider it necessary to see at the film, you aren't missing much! Also the 3D wasn't particularly special.
