Multiple separate storylines succinctly joining together at the end of the show. Wow what a unique concept completely not shared by any other sitcom...
First shared house I was at was great. housemates never there so pretty much living by myself for only 1/3rd of everything. Second time not so much. Dude was super passive aggressive all the time and had his stuff spread out all over the house made us feel like we couldn't have anything out anywhere. Then we found out instead of paying equal shares in bills and rent like we'd agreed to we were actually paying for most of and in case of internet more than shit actually cost.
If they've lasted this longt they're probably fine. Not all of em broke and those that did didn't take very long to do it. It was likely just a couple of batches.
