Downloaded and watched the whole series in the last week. It is quality. It's very hard to pick a favourite character because so many are so good, reminiscent of The Office - Tim, Gareth, David all brilliant for different reasons. Also a brilliant collection of beautiful women - Gloria, Claire (Julie Bowen, who I've been watching for over a decade through 4 different shows) and the eldest daughter (she's twenty, thankyouverymuch)
It's a very strong script, to the point where even the ridiculous, that I normally role my eyes at, is acceptable and funny, examples being the ice skating and the pigeon fight.
If I had a gun to my head I'd pick Phil as the best character, especially from the iPad episode onwards. That episode, Van Gogh, race to the airport, re-enacted honeymoon, basketball games...brilliant.
