I forget where I saw the description but I quite enjoy it, an author was breaking down stories into four general groups: In Melodrama, the hero wins. In Tragedy, the dragon wins. In Comedy, the hero and dragon overcome the root of their conflict, and in Farce they dance around each other without resolving anything. I wasn't familiar with Sideways, but from your description it sounds like I'd call that a comedy being reinterpreted as a farce. Which can be a great story form as well, but maybe it's reached for too often in fan theories because it's the easiest thing to imagine after melodrama.
