I agree with with another reviewer who thinks this might just be the worst Sherlock Holmes ever--or at least among the worst. It's because this version of the great detective is him in name only--almost nothing about him sees like the Holmes of the Conan Doyle stories. Having read all the original stories, I know what I am talking about here. John Barrymore simply isn't Holmes. This didn't come as that much of a surprise, though, as when the movie began it said that the film was based on the plays of William Gillette--not the Doyle stories. Gillette played fast and loose with the character and added many of his own details and flourishes and over time, his plays became less and less like Doyle's stories. So how could anyone expect this film to be THE Sherlock Holmes? The story is a weird variation on the original Doyle story "A Scandal in Bohemia". Of all the dozens and dozens of original stories, this one happens to be my favorite and it's practically a perfect story. But, oddly, very little of the original story remains (just a few odd bits and pieces)--and lots of unnecessary stuff is added. To Holmes maniacs like myself, this is tantamount to sacrilege! A prince has fallen for a commoner. He isn't particularly worried, as there are others in line for succession well before him. However, when those ahead of him are killed unexpectedly, he calls off his upcoming marriage--such a marriage would not be acceptable to the nation. Despondent, the lady kills herself and her sister has letters that the future king had written to his former lover. The British government want Holmes to find those letters and return them to the man who is about to be crowned.
Okay, aside from completely changing the story into a tale involving Moriarty (who, by the way, was captured pretty easily at the end), the story did some of the most ridiculous things you could do with Holmes--it made him a sentimentalist AND had him fall in love, inexplicably, at first sight. Holmes NEVER showed anything but contempt for most women (save two) in the stories and NEVER was sexually interested in any woman--in fact, he was repulsed by them. In THE SECRET LIFE OF SHERLOCK HOLMES the film went so far as to say that Holmes was gay (and fantasized about Watson!). While the real Holmes in the stories seemed asexual, being gay at least made much more sense than having him fall for a lady and even propose to her at the end of the movie!!! This is just wrong and violated the entirety who Holmes was. Plus, Holmes acted more like an action hero and showed little of the usual methodology he employed in the stories. It was as if no one associated with the film ever read the stories--not even one. If all this is okay, why not make him a Chinese acrobat or a serial killing nudist? There was so much more about the film that was wrong or didn't work but I won't bother going on, as the love interest alone ruins the story.
So what is good about this film? Well, it had lots of footage that was actually filmed in London and the scene in the mountains looked nice. Aside from that....absolutely nothing makes the film worth seeing--even if the great John Barrymore is in the lead. Apparently it took many years to piece this movie back together from various sources in order to restore the film. Too bad it wasn't worthy of such efforts! Yes, you can tell that I do love my Conan Doyle!
