I guess you could call it a guilty pleasure. The craziness of the Osbournes as a whole is a hoot, but when you add things that go bump in the night and ET encounters, then ask them their opinions about it, a cup of crazy just escaladed into a blender full of lunacy.
Jack has grown from a lazy, snarky celebrity kid into an interesting bonafide TV host. He's still snarky but it serves him well as an adult personality much better than it did as the bratty British kid of Ozzy Osbourne. Begrudgingly, I have grown to like him. His fashionista sister, not so much. His other investigated shows have been interesting to watch also, especially those with celebrity tagalongs.
I would like to see another season of this show. So keep rocking it, Jack!
