There are a few shining moments in "Jail Bait", in which Buster Keaton treats us to some of his physical magic. Overall, however, "Jail Bait" serves as yet another example of a talkie written, produced, and directed by people who clearly didn't grasp the naiveté and innocence of a genuine Keaton character. They instead produced a mawkish simpleton. He possesses no traits to endear him to us -- no pluck, no wit, no perseverance. His only motive -- love for a girl who clearly doesn't even know he exists -- only underscores the fact that he's clueless, dimwitted, and oblivious. And unlike a real Keaton character, who triumphs due to his own persistence and ingenuity, the hapless hero of "Jail Bait" succeeds only through sheer dumb luck and a touch of deus ex machina.
"Jail Bait" isn't as painful to watch as "Free and Easy", which left me unsure which I wanted to do more, cry or vomit. But it's not a pleasure, either.
