I've watched AI for the past few years, but last year with Menage a Trois and Carey wasn't watchable. Didn't really like much of the talent either. I'll try again this year with the new judges. I have really enjoyed Harry Connick Jr when he's been on as a mentor.
I'll watch some of the Voice on occasion, if nothing else is on. But I only like the part where they spin the chairs around. When they start getting mentored by the stars, it's kinda dumb. (pitting your own team against itself???)
I think the talent on AI is much better than the talent on the Voice. Although the Voice is improving.
I watch Dancing if they have someone on I like. Last couple of seasons, they have been getting down to the bottom of the barrel with "celebrities".
