It was so-so.
The old expendables crew are underutilized, the new expendables are about as interesting as watching paint dry.
Rousey didn't sell the tough chick act very well, her "tough face" made her look like she just smelled a fart, Ortiz was terrible, I know he's not a trained actor but his delivery was terrible, he managed to be worse than Lutz.
The action is very much PG-13. Stunts and fight scenes are quite nice, but every time they hid the bloody outcome of a meeting between a metallic object and a fleshy target by using objects in the scene or through quick editing and camera angles, I couldn't help but think, "this is an Expendables movie?".
I did like Harrison Ford and Antonio Banderas, the latter was hilarious, and the former had a few funny lines that make fun of Statham's speech.
The film's biggest sin however, is wasting Mel Gibson. He didn't do much, and his fight with Stallone was a disappointment, he threw a few punches and then it was over.
Van Damme's Vilain at least went out like a villain.
If I had to rate it, I'd give it a 5/10.
