LOL, the first time I tried to watch the US version (and before I'd watched the UK one, mind), I was completely and utterly turned off by the sex scenes - no chemistry, too glossy, fake, no nada. Then later watched the UK one and was like "DUDE, THAT'S MORE LIKE IT I FINALLY GET WHAT ALL THE FUSS ABOUT THIS SHOW IS ABOUT." Then much much later finally gave the US version another go, and urgh, still the same, can't stand it. I don't think it's one of those things where you can really predict which version someone will like (if if they'll be of the rare persuasion that enjoys both). You just gotta give both a go and find out.
