Do you think Schwarzenegger's return (I'll be Back) to movies is a good or bad? and Why?

I'm a fan of Arnies work you know some of the clics Conan the Barbarian, Terminator, T2, Predator and even some of the cheesier stuff like Commando. But lets face it even before he went into politics his movies were beginning to suck big time (The Sixth Day, End of Days etc). I for one am not looking for Arnies return especially now that he is a lot older, maybe if he appeared in the next Expendables movie that would be o.k. But other than that he is on the path of buddy movies I think (i.e the older seasoned veteran paired with a younger partner who bears most of the stunt and action through the movie). Did anyone else notice this even with Keanu Reeves in Street Kings. Chris Evans had a major chase scene in that flick which normally would have gone to Keanu in his younger days.
