So what is it? I really like the episodes of Red Dwarf that, to me at least with my limited sci-fi knowledge, try and do something different. In reality, the white hole's time shenanigans are relegated to two scenes only, which is fair enough - if it were overused it would become annoying quite quickly. The episode has a simple premise - the ship is out of power, and the crew have an objective to complete in order to sort everything out. Talkie Toaster is more or less the star of the episode, even though he isn't in it very much (like the titular white hole itself). Again, overuse would lead to annoyance. Well balanced with some good gags (using Kryten as a battering ram, and Rimmer's stuff about Captain Oates) was great. One of my favourites of series 4 for a lot of reasons. So what is it?
