Not much I can add but I can endorse the very postivie comments already made. The movie presents a very different Sherlock with enough of teh aspects of teh old Sherlock to make the character entirely believable. Watson was a farther streatch for me in fact than Sherlock. I did think it a bit tedious that Sherlock and Watson faught constantly. Downey is his usualy, smirking, dont-take-me-too-serious actor with the enevitable quips and one liners. The CGI is entirely seemless and does not get in the way in teh least. The plot is very Sherlock-ish and the character development sterling.
The most amazing virtual visual and movie going experience of ALL TIME.
I say that not lightly. I am 60 and have seen my share of visually stunning and this is the top, no, over the top by leaps and bounds. Storey line is OK, character development is sufficient but the engrossing, pull you into the world, realism is not comparable to anything I have wseen. Must see in IMAX 3D. This is ther one thing you cannot get at home and you have to see it to believe it!!!
