Never stopped laughing from the first encounter with the crazed hologram to the end when they turn the tables on Rimmer.
Locations are different enough to provide a change of scene. Dialgoue its its usual high quality full of gags most of which are above medium on the laugh-factor.
Plot is sufficiently engaging to make you stay tuned. There are some real moments in this episode. Kryton doing a schmeee. Lister's "Boys from the Dwarf". Rimmer though takes the plaudits with his virtual insanity episode and his sock puppet.
The introduction of the luck virus just takes the action to a different level.
