I've been watching the show since its premier in September '08 and I must say its only getting better as it goes on. The first episodes weren't bad, they made me watch more. The show cought my attention.
Last night's episodes and the one before that - I loved them. I saw that the show has upped its game, and made me laugh more often. I hope it keeps going that way and we can enjoy a few more seasons of this brilliant sit-com.
