American vs. British Being Human

I've seen several episodes of the American version of Being Human now, and it's really interesting to see what's the same as the British version and what's different. So far I like the American storylines better, but I prefer the British version of the characters over the American version of them. Also, the American version has yet to come close to the sublime "housemate" moments that the British version seems to manage so effortlessly.
