I just got back from seeing it.
A bit disappointed really.
I loved the first one but there seemed to be a decline in the subsequent one and 5 hasn't helped to stop that.
If you just want a visual spectacular then it's worth seeing, the effects are amazing but the story is convoluted and unsatisfying The set pieces are breath taking at times but the come so thick and fast that there is no time to figure out what is actually happening or give you much of a chance to care. The new heroine could have been so interesting and a real foil but the whole movie just swept along so fast that there was no opportunity.
