Having re-watched the entire BBC series this week, there's absolutely no way it will be bettered this generation. I'm not even exaggerating.

I think I TiVo'd this so I'll see how I feel about it. Maybe it'll be a better-than-average crime drama but it won't have anything on the Moffat/Gatiss series. Everything about the BBC version is absolutely perfect.

And yeah the second series finale is just wrenching.
