I'm going with the first because it ended up not making sense to me. It was interesting how they had the old characters come back and speak, but beyond that I wasn't able to understand how Buffy et al could defeat first evil. They can't, so..they fry a bunch of Turak han? Yeah...so what does that accomplish. It's like squashing ants at a picnic. Or was it just a case of closing that particular maw of hell? Or the fact that now 1000 girls in the world can hit a home run in little league?
I felt cheated.
My second choice is Eve because out of the other choices up there she bugged me, like a mosquito I wanted to slap. Bad acting. The role either needed to be played by a great actress who could have done something convincing with the weak material given, or the part written with enough menace for us to actually quake in our boots a little.
The guy who replaced her did a better job, but I would have liked to seen that part really banged out.
