I recently discovered a similar show, Kevin (Probably) Saves the World. It has a similar premise with likable characters. That's the key. Justin Ritter, son of John Ritter, is the eponymous Kevin. His mannerisms are a lot like his dad's, and he does some pretty physical slapstick comedy that is quite good.
Unfortunately there will only be one season, since it has been cancelled.
Aw, damn. I didn’t know it was cancelled. I’ve really enjoyed it.
