Sherlock Holmes was great – lots of action, good interplay between Holmes / Watson and Holmes / Adler. Villain was so-so.
Traditionally, Holmes has been portrayed as a brilliant mind but very reserved–he would never just be in a boxing match for the hell of it. The new Holmes is brillant but a little more vulnerable. He has to deal with his emotions (“losing” a friend to marriage, the reappearance of the only woman who stimulates his, ahem, mind) and is more human than logic machine.
He can solve a riddle before your tongue finishes telling the tale and he can smack the taste out of your mouth before you’d ever see it coming.
