I saw this last night, I enjoyed it.
A lot of the gags and beats were great but I thought the story/plot left a lot to be desired. The bad guys sucked and I didn't like the Spec Ops twin brother or whatever. It wasn't as good as the first, but I think the intent here was to pay homage/celebrate the original. The credits really make it seem like that way too. I had fun with it, lots of great set pieces.
