I thought it was pretty bad..
Let me start off by saying I love Sly. And to be honest, he wasn't too bad in this but...it's time to hang it up as an action star.
The plot was so basic. I mean, without expecting too much from a Rambo movie, I at least thought they would come up with something better than 'Cartel stole his granddaughter (or whatever she is)'.
Also, it's a bit strange that someone with the survival instincts of Rambo would save this girl from her drug dealing father and drive what seemed about 30 minutes over the border and live there with her. Why not take her up north somewhere? I mean all she had to do to find her father was drive an hour and ask a friend.
Stallone's face is so expressionless now, and he can't anunciate very well. This makes for a tough watch. I can still somewhat buy him as a tough guy, but some of his acting was pretty brutal in this.
Cool end battle (though it started to feel a bit Home Alone-ish), not much of anything happening beforehand. Overall I'd give it a 5.5? I dunno. It's hard to give it more than that.
It's watchable, but you kinda have to keep your eyebrows raised to get through it.
