Buffy the Vampire Slayer
Lois & Clark/Smallville
Enterprise

Who is your favourite character from #2? At first, Spock. Now, Kirk.
Who is your least favourite character from #4? I dunno. I don't track that sort of thing. Of regulars in the main title Anya appears in my cartoons least.
What would a crossover between #1 and #5 include? The Doctor arranging his own adoption.
Who is your favourite 'ship from #6? Archer, Trip and T'Pol (AT&T)
If you were to set one person from #3 and one person from #6 on a blind date, who would they be? Because they'd make a good match? Hot Lips could teach Reed a thing or two about loosening up from the family military tradition, since that's all more than he that she knows.
If you could meet one person from #4 and spend the day with them, who would it be, and what would you do? I don't know whether I could spend a day discussing with Giles the influence of the supernatural underworld on the Campbellian monomyth, but I bet he could talk about it for a day.
If you could change one thing about #2's plot line, what would you change? I'd point up more that nothing Kirk's ever done onscreen is violation of a just Prime Directive.
Explain a relationship between two people (not necessarily romantic) from show #5, and why you like the relationship between them. Actually my favorite relationship of Clark's is with Bruce, but Bruce has never appeared on L&C or Smallville. Yet.
If the lead title characters (first name in the credits) from #1 and #3 were both drowning, and you could only save one, who would it be? Hawkeye, because once he was safe I could go back for the Doctor and even if he'd drowned he'd regenerate.
If you could change the title characters' order in the credits for #4, what order would you choose? I couldn't tell you what the order is, except that Buffy's first and Giles is last, till he leaves when Willow's last.
If you were able to add a new character, any kind of character you wanted, to the storyline for #6, what would the character be like, and what would their role be? I'm going to hijack this question to #3, since I've actually thought about that: I've been saying since it happened that there ought to have been a new character introduced when Radar left to keep the show fresh, and that the show's own history is sufficient to make it obvious that not doing so was a mistake. Make Klinger the replacement company clerk if you like (actually Period of Adjustment is one of my favorite episodes); they ought've brought in a new nurse, or expanded Kelley's role then instead of waiting till the end of the series' run.
What happens in your favourite episode of programme #2? Kirk gets to be Hornblower and Spock dies. Regular episode? Kirk gets to be Hornblower and Commodore Decker dies.
If you could kill off one of the characters in #1, who would it be and how would you do it? Ace, apparently. Though I also gave her a long life.
If you got the chance to visit the set for either programme #3 or programme #5, which would you choose? #3 of course. Dude, it's ranked higher on my list.
If you could date anyone from any of these shows, which programme and which person? Well, I'm married. If I answered anyone but Doctor Who's Rose my wife would kill me.
