"Space is boring as hell" - Movies about 'mundane' space travel.
Movies that, at least initially, attempt to deglamorise outer space, whether it's stir crazy space-truckers on interstellar flights, or just people quietly manning a space-station or moon base. Even the stars and the infinite vastness of space have just become a part of their workaday routine. Yawn.
So, whenever you see a bored astronaut - scream (it's okay, it's space - no-one will hear you).
