Its pretty cheesy.
So this show... is interesting. If there was a 2.5 rating, that's what I'd give it. Now, I think Sing On is a good show to watch for a family. Its great for all ages, since they don't sing bad words in the songs. The singing is fine, and the singers are fine, but really not that great. The reason why I said that it's cheesy is because one, just the whole effect of the show is very... game showesqe, which isn't always a bad thing? And two, the host does some very cheesy things like look into the camera certain ways and its kind of funny, but a little much. Most of the contestants are nice, but some are quite competitive. There's nothing to worry about inappropriate wise, but I'd say that to really enjoy it, your child (or you) should be 6 years old or older. I wouldnt recommenced this show, but if you'd like to try it, go ahead!
