Normality? No, I don't think I'm familiar with the concept

As soon as I saw the name Stephen Moffat on the opening credits, I knew it would be good. And I was right. Sherlock's got just the right sort of lunacy, and Watson is a perfect source of mixed bafflement and enthusiasm. There's lovely bits of dialogical non-sequiter that actually make perfect sense, and I've never seen Jeremy Brett be that funny as the World's Greatest Private Investigator. And the out-of-scene devices to let you know just what's going on (the map, the texts) are are beautifully done.

Holmes pickpockets LeStrade when he's being annoying! :D
