A while back, Lady Bling tried to get me to watch the new BBC version of Sherlock. She explained the premise. My response: "Update Sherlock Holmes stories in the modern day? What a terrible idea. Seriously." And it was on PBS's Masterpiece, which is almost always stuffy period drama crap that I don't care about. But then one day, I caught the end of the first series finale during a rerun she had on in the background, and thought, "WHOA. What have I missed?" As it turns out, a LOT.
The scripts, the casting, the performances, the editing .... it's all top-notch. So I bought the first series on Blu-Ray and it's amazing. Each series is only three episodes, but each is 90 minutes with no commercials, so it's like watching three movies. The first two episodes are very good, but the third is outstanding. Then we tracked down the second series (which is already on region-free Blu-Ray in the UK but won't be on PBS in the States until May). It's even better than the first. The premiere episode (A Scandal in Belgravia) is some of the best television I've ever seen, and the finale ends with a cliffhanger that has large pockets of the internet trying to figure out what happened.
She won't get me to watch Downton Abbey though. A man's gotta draw a line somewhere.
