Finally saw this, as our fleapit has it this week. 10/10 - wow. A different interpretation but just as valid to the stories; a slightly different tone for Guy Ritchie... RDj is the best Holmes since Brett, Jude Law is the best Watson since... Um, is probably the best Watson, end of. The movie overall is the best time I've had in a cinema since Star Trek back in May, and probably the best theatrical Holmes movie since the Hammer version of Baskervilles...
It had lots of lovely references to the original stories (directly quotes from many, including The Man With the Twisted Lip, and the Boscombe Valley Mystery) as well to other screen incarnations - even knocking off the Brett version's title sequence's crane pan through Baker Street
I had a couple of minor niggles - Watson should be a better shot, for example, but overall it was bloody great! I fear Moffat/Gatiss' version will have a job catching the right mood as well as this (unbelievably) managed to do.
I want Gladstone to have a bigger role in the sequel...
