My only major complaint was the CG for the future battle which I thought was pretty poor. The Sentinels movement was 'spongy' and without weight and heft.
Too much Wolverine (for me).
Not enough Prof X and Mags scenes together (past and present).
I thought the CG was great compared to the effects in the OT. The only part I cringed at was the scene where Magneto rips apart the train tracks. The lighting made it so obvious that he was just standing in front of a green screen.
