heh, I saw the thread title and it made me start thinking about very very asked questions, some of which have been mentioned.
These are actual questions real life people have asked me:
Why did they get rid of Kes?
How come everybody can understand each other?
Are that Borg chicks boobs real?
Why did Enterprise get cancelled?
Don't you think that TNG is far superior to all that stuff that came after it? (I've been asked this many times, in some cases TOLD this LOLOL)
Is there going to be a new movie?
How 'bout that Captain Kirk eh? (referring to women, of course)
I can't think of a single question or comment anyone has made to me about DS9.
You forgot "WHAT HAPPENED TO THE BORG BABY??"
And a bajillion questions about the alternate timeline in JJ's movie.
