"Taxi Dolls" is about robots that are incredibly lifelike. One wanders off to a taxi and the inventor retrieves it. Due to a mix-up a real woman is mistaken for one of these weird automatons and hilarity does NOT ensue.
By 1929, silent comedy had been perfected and many wonderful films had been made. As a result, the standards were a lot higher--no more mindless firing of guns, bonking people on the head and the like. And because of this context, I am a lot tougher when I review these films than when I review the very early comedies of Sennett and the like (which, mostly are people bonking each other!). After all, by 1929, Laurel & Hardy were an established team and patrons wanted more. SO, not having the usual bonking in "Taxi Dolls" is nice--too bad they didn't spend more time working out the comedic aspects of the film. Sure, i has a cute plot, but it isn't all that funny.
