I hate Deanna Troi, more than any other character from any series ever. (All series that I ever watched, I mean it. Ever
I don't care about Spock or any other Vulcan whatsoever, besides Vorik and TOS Sarek.
The whole Klingon concept of Honor bores me to no end.
I don't think Data is all that great of a character.
I think most of TNG plots were terrible, even though it's still my favorite series.
I think Garak is overrated. (I did loved him first I watched DS9, but then he just meh'd me)
I think Barclay is much more interesting than more than a half of the TNG's main cast.
I find Worf 80% of the time just comic relief and the other 20% he's either being way too awesome, or way too annoying.
I find every Q episode to be particularly bad exactly because Q alone is my favorite character.
Ezri's character was terrible, but I sort of like the way the Natalie(?)-what's here name- portraits her.
I think Weyoun is cooler than the whole DS9's main cast combined. Twice.
