People often say you need conflict to tell a good story and I feel that's kinda true to an extent, but if you've got good enough characters and write them well enough, anything can be entertaining - even going to the store to buy some milk or hell, watching paint dry! - but you probably would need to get the reader/viewer/listener invested in the characters first (hence why "fluff" generally works better as fanfiction or one-off episodes of TV shows) and would need characters more fit for mundane situations.
