My answers (feel free to share yours ☺ ) :
1) Best season of BTVS : Season 6.
2) Best character from the original Scooby Gang : Buffy Summers
3) Best recurring female character : Dawn Summers (I adore Faith & Willow too).
4) Best recurring male character : Spike! (I don't know why I'm still surprised to find him that far ahead).
5) Most underrated male character : Jonathan Levinson.
6) Most underrated female character : Kennedy (Yep! Even if I, of course, really like Joyce and Drusilla)
7) Least favourite character : Kathy, because she was annoying, but Parker definitely is the jerkiest of the two (Dawn's first position in this poll still feels unjustified and incomprehensible to me).
8) Favourite OMWF song : "Walk through the fire" (special mention for "Rest in Peace" and "Something to sing about").
9) Greatest Big Bad : It was a hard choice, I like equally Angelus, Glory and Caleb. I voted for the latter, but I could also have voted for the other two.
10) Best Minor Villain : Turok-hans, because they were impressive. (I don't know why the Trio is mentioned in this category though, I think they fit better in the previous question).
11) Couple that gives you the most feels : Spuffy (duh!). Interesting to see that Willara is in the lead!
12) Who do you ship Buffy with : Spike (no surprise here :) ).
13) Death that has the biggest impact on you : That one is hard to answer. I voted for Buffy because I cried for days when The Gift aired in France, but the death of Tara and Joyce also had a huge impact on me, on a longer term, since Buffy came back.
14) Quote which is the most memorable : I could have voted for all of them, really. I finally chose "The hardest thing in this World is to live in it. Be brave. Live."
15) Which season finale is the greatest : Restless is my favourite episode of the show, but if it's an excellent episode, it's not a good season finale. So I voted for Chosen.
