This review is going to be exceptionally lazy – this review from Pajiba sums up my thoughts quite nicely. And omg, the first paragraph created some nice visuals in my head. So, read that.
And yes - stay till after the credits. Highlight for spoiler:
A S.H.I.E.L.D. agent investigates a huge crater and finds a hammer.
So, we’ve got a solid, fun action movie that’s not quite up there with Iron Man.
4 out of 5 Stars
