Not Great - SPOILER
This isn't a bad film, but it's nothing special. It's a pretty predictable action film. The one big surprise, if you can even call it that, becomes painfully obvious about 30 minutes into the film, and you're left waiting for Stallone to reveal it and get it out of the way.
As color-by-numbers action films go, it's fine, but there's nothing clever or thought-provoking here.
Also, it isn't clear how strong or invulnerable Stallone is. At one point he's hit by a car, which knocks him out and leave him with countless broken bones. He wakes up and heals quickly, though he then needs cold water and ice cream to stay alive. Later he's shot about 200 times in the span of a minute, and doesn't flinch, and repeated blows to the head from the magic sledgehammer don't seem to harm him much. Why was the car able to do so much damage?
The movie is full of inconsistencies like that, down to the end in a flaming warehouse that refuses to collapse, and apparently contains no smoke.
Worth watching if you want mindless entertainment.
