Kutcher is a crappy actor in my opinion, and besides Charlie is the one that made that show great.
I dunno BC, I discovered 2.5 Men reruns about a year ago while dealing with some depression. I discovered 2.5 Men was an hour of pretty mindless, completely predictable distraction. Both leads and even the kid can act fine but it's the comedic shots that make it funny. Bertha seems to get the best lines.
I never watched Ashton do more than act dumb (which he does as if he is) so actual acting will be a bonus.
Charlie Sheen is likable but he just threw a tantrum on a National stage and sold tickets to it.
