Poor Lister. Stuck 3 million years in the future, light years away from Earth. Everyone he's ever known or loved is dead. The girl of his dreams is dead. His only companions are the hologram of his bunk mate, who he hates, and a creature who evolved from his cat, who acts like, well, a cat. And to make matters worse, he's just found out that he is the God of the cat race, Cloister the Stupid. Worse that that, the cat race had, years ago, had a holy war between two factions - over the color of hats. Mind you, religious wars have been started over much dumber reasons. And one of those factions had actually left the ship in pursuit of Fushia - the mistranslated Fiji, where Lister had longed to retire to - and ended up all dying in a crash, following the directions left by Cloister, which was nothing more than Lister's laundry list. Lister ends up meeting the only other remaining member of the cat race, a blind old sage who followed the ancient religious texts donning custard-stained clothes and being a slob. Lister tells him that he lived his life well, just for the old cat to pass on.
Rimmer, on the other hand, is intrigued by one of the ship's garbage pod which has been caught drifting in space. Lister and Holly both know what's inside, but leave Rimmer to his quest to find out who these ancient aliens were, and maybe meet them. The episode ends with Rimmer finding out just what treasures await him in the alien craft. Truly a great episode, and the turmoil Lister feels realizing that he is a messiah figure is very reminiscent of Life of Brian.
Overall, I am going to have to give this one 9 roast chickens out of 10.
