A pretty good series, heavily watered down by them playing silly buggers with the final hour. Yes the "John Leslie" bad guy was funny and they get major kudos for the Robocop reference but other than that the episode was a sad (as in poor) end to a good series. Let me break down the final hour:
First 10 minutes: As predicted Gene is a tumour. Kill him and you can escape.
Main 40 minutes: Erm, we don't have anything left. No one believes he is really in '73, so let's hope to fool some gullible person with an overview of the main themes in Total Recall (you know, the film Paul Verhoeven directed right after Robocop). Hell, Total Recall was even set on Mars!
Introduction of key information minutes before end: Barman says "you'll know it's real if you can feel it". Slightly later than normal episodes but it is the last episode.
Final 10 minutes: Need a final ending. Okay, let's rip off not-very-well-known Spanish film Abre Los Ojos. Oh wait, didn't Tom Cruise remake that as Vanilla Sky and even have the top-of-the-building shot, panning around before he runs and jumps? Damn, let's hope nobody notices.
Very final thought: Actually, I prefer the dream world of 1973, I'd rather give in to the tumour and die than live in the current day.
My initial reaction was the ‘waking up’ segment was actually a dream, or lighter part of the coma, which he experiences as they come closer to saving him. The then rejects it and gives in to the deep coma and death. It seems the writers didn’t mean this, they meant to show that he did wake up – meaning the ‘I can’t feel a knife in my thumb’ scene was just contradictory as it was real. He then kills himself by jumping off the building so he can have one last second in his imaginary world (which will last an eternity in his mind) before he dies.
I haven't seen a final episode as bad as this since they destroyed eleven year's work with the final five episode story-arc of Frasier. Tonight's episode was "written" by the co-creator so they no one else to blame other than themselves. A very sad way to go out.
