I liked it but maybe not as much as the first.
Some Spoilers:
I thought Jared Harris played a great Moriarty and there was some genuine chemistry in the scenes with hime and Holmes.
The inclusion of Irene Adler was kinda pointless.
I like some of Holmes crap disguises :-)
Moran was clearly not a gentlemen now way did he get an accent like that in Eton and they'd never let an oik like him become a Colonel. He'd wouldn't be let into the clubs that he would be later thrown out of :-)
On a side note, phantomstranger. Have you read this, its a nice light hearted take on the Greatest Consulting Villian with some mention of that Baker St dectective too:
