He comes across as really happy and down to earth while still being naturally hilarious. A lot of comedians aren't as funny offstage but Carrey sees everything as material. If I could have coffee with one comedian from this show it would probably be him. I liked his paintings a lot too.
I agree with others that this show should be longer. A lot of the dialogues seem forced simply because they're edited so much to find jokes and interesting quotes. I'd love to see an unedited episode.
