I have to agree with other commenters that this was a poor choice of films for Buster Keaton. The early part of the film is disappointing, as it provides Keaton with no opportunities to do the amazing physical stunts he's rightly famous for. I found it dismaying to see Keaton, who flipped over the rigging in "The Love Nest" and made the clotheslines his playground in "Neighbors" deflated by a half-slack garden hose.
But the hotel sequence, in which an amazonian blonde tries to teach Keaton's pathologically girl-shy character to be a real Casanova, turns things around. "Buster Keaton" and "screen kiss" are two ideas that don't seem to go that well together, but Keaton turns the combination into something that's purely his. Like the climax of "Steamboat Bill Jr.", Keaton's character finally seizes control of a situation where he's previously been a victim of circumstance. Suddenly he figures out how this works and charges ahead in his own unorthodox, exuberantly acrobatic way. And that moment is worth waiting for.
