Ya, I actually really like season 7, it had a lot of potential but fell a bit flat. For me it was the lack of resolution and continuity, they did have stories for Willow, Xander and Giles but decided not to use them.
1.Do a few episode where they show Willow grieving Tara, for Christ sake did she just forget her or something. We get the Killer in Me, which by the way is one of my favorite, but that's not good enough. They could have shown Willow struggle a bit more, have her friends be there for her you know. Also, I won't even get into the addiction storyline, that fell flat on it's face too.
2.Giles may not have been relevant much the past few years, but they are bringing in a bunch of potential slayer and you have a man there that is exactly qualified to be a trainer and yet it's Buffy that trains them. It's not because you're a good fighter that it means you're a good coach, get Giles to do the training, get him involved. Get the Scoobies to hug him when he gets there, I mean that was just a cheap storyline, no one would NOT have noticed if Giles didn't touch anything, come on the guy has to eat and go to the bathroom, he sits and sleeps, he would be shown touching something!
3. Xander, oh poor Xander, he's somewhat always been in the background so I don't mind him being in the backgroud too much, I kind of like him better in that role anyway. It is shown that the only reason he sticks around is for Buffy, even he knows he's not the most important. Only thing I would have done differently is include him in CWDP, it felt weird to have an episode without him...just not right.
