The Expendables movies are supposed to be cheesy throw-backs to the old action movies. In this they succeed very well. Not much face time as expected for the old crew, which was disappointing because Terry Crews is flat out fun to watch and Dolph makes an awesome grumpy big guy. That's what I enjoyed about the first two movies, the larger than life actors I remember from my youth and the "catch phrases" that came with the action movies.
They aren't suppose to be believable and the dialogue is tongue-in-cheek. Which is why the movies are fun.
Best lines of the movie:
Wesley Snipes' response to why he was locked up "tax evasion", said with an psychotic grin.
Stallone's answer to Statham's query about "what was that?" during the first skirmish. "A large black man in a boat".
although there were lots of others that made me chuckle.
Mel Gibson still has the best "crazy eyes" in the business, evoking Lethal Weapon memories. He's not as fun to watch as Van Damme was, but pretty darn close.
