Hope is not the belief in happy endings. Hope is the conviction that something makes sense, no matter how it ends. (Vaclav Havel) and
I disapprove of what you say, but I will defend to the death your right to say it. (Evelyn Beatrice Hall explaining Voltaire's view on freedom of speech)and if a quote from Star Trek was meant:
There's coffee in that nebula. (Janeway) and
I'm not gonna do anything about it. You're gonna sit in the closet. (Uhura) and
Careful what you wish for, Lieutenant... (Torres) and
Assimilate this! (Worf)
17. Favorite movie SFX - difficult. The travel sequence from Contact? The time travel from Star Trek IV?
18. Favorite TV SFX - difficult too. TOS transporter? It's so cute.
19. Empire or Rebel Alliance - Rebels. As an Ewok.
20. Favorite adaptation of a novel - Ronja Rövardotter (an exceptional example of doing a book justice with a movie) or maybe I Robot because it made a great movie story based on/linked to several short stories.
21. Novel you wish were adapted - actually can't think of one now. But researching it, I found movies I can put on my watchlist because books I thought about actually already were adapted and I just didn't know :-)
Do comic series count? Then definitely Yoko Tsuno.
22. Favorite author - H.G. Wells, Isaac Asimov, Douglas Adams, Terry Pratchett, Diane Duane, Victor Hugo, Astrid Lindgren, Michael Ende, Erich Kästner, Mary Wollstonecraft, Marilyn French, Susan Brownmiller, Simone de Beauvoir, V.E.Pilgrim, Alice Miller

24. Favorite Captain - Star Trek: Janeway and Picard / Other: Taggart from Galaxy Quest
25. Funniest - Movie: Cool Runnings. Comedian: Trevor Noah and Samantha Bee.
26. Favorite battle scene - I dislike battle scenes. I always get confused. Maybe Spock against Kirk in 'Blood Fever'.
27. Favorite Dr Who Companion - not my franchise, so I really cant answer that
28. Favorite piece of memorabilia - my very first stuffed animal. It's a yellow egg with hands, feet and face and it sincerely believes someday it's gonna grow up to be a dinosaur. It told me that when I learned to speak.
Star Trek related: a handmade mini-batleth I got from a friend in my teenage years.
29. Favorite pre 80s sci-fi - Star Trek TOS
30. Favorite theme/OST - MacGyver TV series
