In this documentary you mean? I watched it yesterday, and not to armchair diagnose, but it doesn't seem to me he's better. I know his girlfriend died of over medication which he blamed himself for. Hence that really weird interview at an even the gave earlier this year. It's hard to judge based on this documentary due to how it's executed and its editing juxtaposed with Carrey now, but just looking at Carrey in the interview stuff himself he seems like he's totally disengaged. I don't know if this is the healthiest way to be. To me it just seems like fame and everything ****ed him up.
I just think it's better to be concerned than to say he's fine because it's just strange behavior, even if it's a normal person. Unless he's enlightened in a way that nobody else is (unlikely given his status) than I think his behavior is worth being concerned about.
As for the documentary. Aside from some touching moments, I just couldn't get over how much of an ******* Carrey was acting. As if Andy Kaufman was actually whispering in his ear and "took over" Carrey. I think he might be so far up his own ass it's more of a retreat from the reality he might have been struggling with and his deeper problems and this was a way to cope. What an inconvenience to the crew where they had to humor him. I couldn't even call it method acting which I think is stupid. Now could have this been the point of the documentary? Yeah, as these things are usually supposed to be objective, but it just personally annoyed me how much of a pain in the ass all because Andy Kaufman meant so much to him.
