Saw the Blu-ray. It's what you'd expect, silly, goofy action with some good laughs.
If you want a movie that harkens back to the 80s action movies, makes a lot of references to specific old movies in the script, this is it. There more Bruce Willis, more Arnold and in this one even some Chuck Norris.
Unfortunately what I liked about the first was a lot of the banter between Jason Statham and Stallone, this Expendables 2 is in too much of a hurry for that.
The audio is great, what you'd expect - lots of big boom. But the video is disappointing for a new movie on Blu-ray. Lots of grain is exposed in shadowy scenes.
Still a silly fun movie with the biggest collection of living legends since the disaster movies of the 70s.
