Never before has sci-fi and comedy worked out for the mass audiences. And since "Red Dwarf", it hasn't happened. The characters diverse in personality, the sci-fi concepts rich, the humor is riotously successful on many levels. What's not to like?The DVD quality is in top form (with, as usual, a surfeit of bonus material that alone justifies the <$30 pricetag), as alone does the restoration effort (Red Dwarfs 5 and 6 NEVER looked so good) so I will concentrate on the episodes themselves:1. Holoship. Rimmer, a hologram, sees potential for having a life at last on board. The problem is, he has to beat his opponent. Who happens to be, unbeknownst to him, the hologram he falls in love with. Great series opener in terms of irony but the best is yet to come...2. The Inquisitor. A rogue simulant (half man, half machine), wanders Time. Upon the individuals it meets, it assesses them. If they fail the assessment, they are removed from history and replaced with someone else. The story explains it with much more panache. It seems weird as to who passes and who fails the test, but not only does it appeal with its intellectual supremacy, but it remains true to its roots as being a comedy and makes this one a real winner for everybody. GREAT stuff.3. Terrorform. Kryten and Rimmer crashed Starbug onto a "Psi-Moon". Kryten escaped with a helping hand, but Rimmer becomes a prisoner of a world that had been created out of his subconscious state! This one, like The Inquisitor, is riotously funny and appeals to all levels. Best of all, one can feel sorry for Rimmer.4. Quarantine. Another winner, the Dwarf crew (sans Rimmer) happen upon the results of unique experiments. Unfortunately, one of them was a hologramatic virus that infects Rimmer when he radios the crew. Upon the crew's return, Rimmer seems a changed - and eminently insane - hologram. There are some unusual but wonderful concepts here, and Rimmer gone nuts is hilarious. Another episode in top form.5. Demons and Angels. Food supplies are running low, so Kryten perfects a triplicator. Well, not quite. The device takes one object and extracts it into its pure good and pure rotten components. Lister tries putting the machine in reverse and subsequently destroys Red Dwarf. Well, not quite. Two new Dwarf ships are created: One good and one evil. The problem is, to rebuild the triplicator to merge the separated ship, they have to go to both ships... Now while the "goodie" side is a bit goodie, the REAL fun begins on the evils' ship. Indeed, I'll never look at Rimmer in quite the same way again! Devilishly funny, this one also works well.6. Back to Reality. Fleeing from a 'Despair Squid', the Squid apparently destroys the Starbug probing the planet. The foursome wake up from what seems to be a game they've played for 4 years, called "Red Dwarf". This is a GREAT season finale (though the best one ever is a tie between "The Last Day" and "Out of Time".) I won't spoil the outcome, but I will say that Dwayne Dibbley is introduced. A character who gets reused later on, for no reason other than to fill out a horrible episode's time allotment. (A great parody character meant for one episode really isn't meant to be re-used...)as usual, the extras and disc quality are all top-notch.Apart from season 2 and the show's opener episode "The End", season 5 is definitely one to hook potential fans in. It's got EVERYTHING and more.
