I really loved this show. The writing from Russell T. Davies was great. All the tension between Stuart and Vince, and the other characters, was fantastically created through the writing and the cast's performance each episode. One issue, though this was completely personal, was the accents the actors had. I'm not completely familiar with British accents, coming from Australia and all, and I had to watch certain scenes several times to work out what they were saying. Also, the ending wasn't as satisfying as the rest of the series, but I loved it all the same. This, the original, was much better than the US version.
P.S. Vince Tyler is the coolest gay character ever!
