I actually thought A Study in Scarlet ('33) quite good. To be sure, Owen is physically no fit for SH, but he tries his best, and I think he's fine. Robert Downey, Jr., and Ben Snyder compete for the spot of my second least favorite Holmes. The Downey Sherlock Holmes was fine as a film, but Downey himself is one of the least Holmesian of all cinematic Holmes. Like Owen, Snyder is a terrible fit for Holmes, but he does try to his best. The movie stinks, though. My vote for the worst Holmes, however, goes to Matt Frewer, who has been mentioned here before. He is a complete, overacting, scenery-chewing mess, and his line readings are all wrong. Lord knows why the directors didn't try to rein the guy in, but I was embarrassed just to watch his acting. It's bloody terrible.
