The pilot episode, which I watched with my younger son, was good, but the characters did overact a bit. Even shows like Seinfeld and Friends took time to develop. I might increase this score if the show gets better within time. SodaDog has a point, it takes time for the writing and acting to develop.
My younger son loves the show however. Older son is a lot harder to impress.
UPDATE: After seeing more episodes I have decided to raise the rating from 8 to 9. Brain-A-Rooney was excellent. It was relatable with the mother being just like me as far as being a lover of things is concerned. Disney4life and jm5189 are right, it deserves a higher rating.
UPDATE AGAIN: I'll give this a 10 just to increase the average. Last update was on July 15. And I'm looking forward to Season 2 tomorrow!
