i love red dwarf . the basic gist of the show be dave lister and the last human alive and try to make his way back to earth . ( honestly and it make sense if you watch it . ) he be the last surviving human and only remain member of the crew of the jupiter mining corporation ship red dwarf . trap 3 million year away from earth and dave have only three companion to keep him sane represent arnold rimmer and a hologram projection of a previous crew mate while holly and the ship senile and generally rubbish computer while and cat and a humanoid creature who evolve from lister pet cat . all sound very confusing and doesn not it . but believe me if you watch it and everything will make sense . in the third series and the crew be join by an android and kryten and who have a manic obsession with cleaning and help and which lead to yet more hilarious consequence . their escapade take them to all sort of mysterious planet and culture include those of the gelfs and psirens and even a backwards version of earth . but will they ever get back to earth .
