If I read the other reviews as if I wrote them . . .

Rating: 10/10 (30 April 2015)

A neg review made me want to write a pos review . . .
it said, 'Avengers 2 AOU was meh and unremarkable...'
-then said, 'it was another soul less comic book movie...'
I don't remember many comic books having 'a soul'(besides your basic story line arcs that contained a character with a soul.), so I think it deserves more credit than this one negative reviewer gave it.
I enjoyed the 3D version as much as any other big budget hit with specs required to get the full effect. (I actually plan on going to IMAX for Star Wars:TFA)
Without a spoiler this would not be as fun: Thor has a lot of ego while not explaining why the hammer can not be wielded by any other hands but his own. Then another hand not his own (near the end battle scene) surprisingly hands it off right to him. The character is not known to me by name but I will only say that it was sort of Thor's kin, so it actually made sense but he shrugged it off as tho it was a sign from the gods that the new hero could be trusted now. Yay! It is a pleasant twist at a time in the plot where 'a twist' is most worthy.
