I watched it.
I've heard a lot of people saying that it wasn't that great, but I don't agree. It isn't the same, there's no doubt about that, but I think Ashton Kutcher will add a new element to the series. The only part that I really didn't like was that his character just decided to buy Charlie's house and let Alan live with him. It doesn't seem that realistic, if you ask me, but that's just my opinion.
