Now if it was actually being directed by Rodriguez, I would be excited. But actors don't make a movie, especially in an action film where you could replace them with anyone and you'd still have the same damn movie, unless it stars Jackie Chan or someone else who does their own actual fighting stunts and whatnot.
It comes down more to the director and writers to make the movies good. And who's directing and writing this one? Why none other than Stallone himself, who gave us such gems as all the Rocky movies except the original, and that's about it.
I'll watch it eventually, but not in theaters.
Now you know what action movie I AM excited for? Machete.
