The second movie is worse. I literally fell asleep during the last 30 minutes. I still don't know how it ends.
I thought Sly did a great job bringing back Rambo and Rocky, but this Expendables experiment is pretty weak. The first one is sorta fun in a dumb way, not a terrible boring Saturday night rental or Netflix stream. There are way worse movies.
But the second one doesn't even know how to juggle the cast it has, despite some of them only being in it for very short periods of time. Stuff like the Chuck Norris cameo, where it's being sorta self aware of how ridiculous it is being, it just doesn't work.
You can have a big macho explosion movie and have it still be interesting. Expendables 2 was not that movie.
