Having seen the first few series of the British Shameless, but not any of the US version -
from what I've heard, the value American Shameless totally rests on how much you appreciate William H. Macy. As a fan of his, and as a HUGE Coen brothers fan, I think I'd like it. But if you don't really dig William H. Macy, from what I've heard, you won't dig the American Shameless at all.
One of these days relatively soon I plan to catch up on the British version, and then start watching the American. I'll give my little bit of criticism that I can, when I do. But I can definitely say that I've LOVED what of the British version that I've watched.
