Have the same general feelings as others. Right now Kutcher's character seems kind of 'wooden' or incomplete. And while it was neat seeing all the women at the funeral and the cameos, the flow was definitely off with Sheen's absence. Unless Kutcher's character improves, I can see this show fading REAL fast.
Perhaps Sheen does turn Lorre's tin cans into gold......

And while on the subject, I think it'd be in Lorre's best interest to quickly move away from Charlie bashing (more Sheen than Harper) otherwise he'll quickly turn into the 'bad guy' in this little soap opera. Sheen has started his image rehabilitation with the 'I'd have fired me' and kind words and attaboys to Kutcher, so it'd be smart for Lorre to at least move on.
