Charlie Sheen doesn't think Ashton Kutcher sucks. He just thinks the show he's on does.
Several days after Sheen called in to TMZ and went off about the state of "Two and a Half Men" and his replacement, he took to Twitter to make nice with Kutcher, taking it all back...well most of it. Sheen apologized to Kutcher, saying "I was disrespectful to a man doing his best. I got excited and threw you into a crossfire." However, he stood by the rest of his original statement, the whole "I'm tired of pretending the show doesn't suck" part.
No response from Kutcher yet, but he can't be too mad. It was Sheen's big mouth that helped Kutcher land his lucrative gig in the first place.
