Easily the star of the episode, though, is Danny John-Jules as Cat. Seeming far more comfortable in the role than he has for a very long time, Danny steals pretty much every scene he’s in, thanks in part to a script filled with some classic Cat lines.

One of the most talked-about aspects of the new series is the return of the live studio audience, and the difference is palpable; all of the Dwarfers have a sense of energy and fun in their performances that can only come when there is a crowd to seek approval from; and there are several jokes whose timing is visibly improved – one early Rimmer gag in particular is clearly drawn out for a moment or two longer than it might have been without a second wave of laughter to guide the performance.

Also returning after long absences are model shots, as well as specially-composed incidental music by Howard Goodall. As always used to be the case, these are used sparingly but effectively; Goodall’s score adds an extra punch to the scenes in which it appears, particularly towards the episode’s climax. And the model shots are little short of beautiful; this is Red Dwarf for the high-definition age, and clearly a lot of love and effort has gone into making the small rouge one ship-shape (pun intended).

The design is actually stunning all round; as you may have seen from the trailers, the action takes place in a more confined area of the Dwarf, redder than ever before. And it’s hugely detailed, with monitors constantly showing information and intricate set details that before would have gone unnoticed; if one series is going to persuade me to buy a Blu Ray player this year, it’s Red Dwarf X.

Trojan isn’t a perfect episode of Red Dwarf; there are a few jokes in the episode which are played a little too broadly, and at times the Lister subplot wanders into mediocre observational comedy. There are also a couple of slightly jarring references to 21st century life; that said, the first series of Red Dwarf alone contained references to Moss Bros, Kevin Keegan, Helen Shapiro and Norweb, so perhaps this is simply another aspect of the show’s early days making a return.
