Aw, I am actually liking Carson now (he used to annoy me on TRL or New Year's Eve specials). I like that he seems more human as host, such as hugging the contestants, complimenting them, and his banter with the coaches. It's obvious that they hang out off stage, which is nice to know. And every once in a while he will throw out some funny lines, like when Tessanne had to sing right after her win and he said something like "Okay now you've won, right back to work" and then shoved the mic in her face.
I thought it was a good way to make an awkward moment funny.
