Redz, Shameless is an American incarnation of a British show by the same name.
I've never been one of those "the British version is always better" guys, and in fact I don't really like the British version of the Office.
But I'm 2 epis in on the American show, and so far it fails to replicate the certain "feel" of the British one. I ripped through the British first season in like 3 days.
