Bargaining Pt 1&2 - Great two-parter. But I don't know which one to choose if I vote for this one.
Life Serial - It is a funny, light-hearted episode. The Trio aren't so evil yet (But I think what Warren did to Buffy was very, very scary. I really don't like Warren.)
Once More With Feeling - I love musicals, so I love this episode. There are some inconsistencies, but I can forgive them. I will not choose this episode for the poll due to the same reason why I didn't choose Restless and Hush for S4 thread. Songs themselves are character-centric and important plot devices in the episode, however it is not fair for other episodes to choose it, since its main charm is its unique structure.
Older and Far Away - I enjoyed this episode. Just when S6 started to drag too much, it came to the rescue.
Normal Again - It is a horror episode and deals with the urge to run away so well. I like it.
I choose Life Serial, Older and Far Away, and Normal Again.
