MINOR SPOILERS BELOW
This was a pretty poor read, only saved from a zero-star status by the presence of some strong art (Jeanty, Owens, Madsen, I love your style - even when the subject matter is idiotic) and the fact that you can't leave less than a one-star review.
Despite my misgivings, I was willing to push on and see if the plot that had begun to go badly awry in TBP 6 could be leading to something interesting and emotive, or at the very least salvage the characters and story line that years and years have gone into building up. Sadly, this was emphatically not the case. Stale writing, smug self-referentials, and a pretty stunning lack of substance and credence in the plot dragged the book down badly. This despite the much-announced arrival of Angel in Season 8, and the revelations of the real meaning of Twilight.
Even the fact that Joss Whedon wrote the intro chapter doesn't save this, and honestly I found even his contribution ('Turbulence') to be anti-climactic. The dialogue was sharper, but the focus was entirely off. If 60 pages of the TBP focus on Angel and Buffy, 40 before them focus on a completely ill-timed and irrelevant love rhombus between Dawn, Xander, Superpowers and Buffy. The relationships between characters has been a great source of interest, humour and pathos in the comic series... but when more pages, words and effort are devoted to dealing with a jarring romance subplot than to finding a suitably clever or heroic defeat for the three giant monster goddesses that just killed hundreds of people... the flow of the story just falls apart.
Speaking of the flow of the story, the exposition-heavy nature of the story's main dramatic scenes was badly handled indeed. Most tellingly, in the long-term: the stuff that is expounded upon has never even been mentioned by anyone or anything in any of the comics before now, mythology-wise I'm afraid the whole thing comes across as ridiculous even when the writer clumsily tries to use Giles's Watcher status to ret-con it all into the arc and the backstory of the entire Slayer legacy. But also, in the short-term: everybody spontaneously gets their powers back/gets to be invulnerable/gets healed/gets ignored/gets left in Tibet etc - with no effort made to explore how or why this is going on, all just to set up the big finale scene.
And thanks to all of that, there wasn't a single page or even a single panel of this collection that raised a smile, gasp or laugh from me. The closest I got to believing there were actual characters and people behind the unsurprising dialogue and cliche situations involved Warren and Andrew, Xander's penultimate line, and a sliver at the end of the horribly over-extended scene with Buffy and Angel. It's not because I'm cold-hearted or anything, either. I've laughed and gasped and been saddened by many a venture over the course of Season 8, but not these past issues. No way.
So there's no way I'll be buying the TBP 8 of Season 8 unless somebody convinces me that a grown-up has control of the plot, no matter who is putting their graphic art skills to it.
