Facial expressions and timing. Two families that aren't fond of each other happen to be neighbors. When the son of one family (Buster Keaton) falls in love with the daughter of the other (Virginia Fox), it isn't long before both families are up in arms and misunderstandings become escalated. Honestly speaking, Keaton has yet to let me down, and even his twenty minute shorts never fail to get uproarious laughter out of me. This is laugh out loud physical, slapstick humor, and while I typically react negatively when I see this in my modern movies, it just ends up being wildly charming in silent films. Buster Keaton is fearless in sacrificing his body, and he performs stunts that will make your jaw drop; when you get to the ending where they are doing a human totem pole, you know that couldn't have easy, or 100% safe, for that matter. There are a couple of racial things that aren't really cool, but that's just a sign of the times, as this was released in 1920. This is just another winner from Keaton.
