Above and beyond all others, "The Girl In Question" should have been shelved as soon as it became obvious that Sarah wasn't going to be able to reprise her role as Buffy. The story was totally useless, and came at a time when everyone knew that "Angel" was going to be canceled. The mission to recover the head in Rome might, and I emphasize MIGHT have worked simply on its own merits, especially if the mysterious Immortal had been confronted and had given Angel, either willingly or after being vanquished, some vital bit of information about either the Senior Partners' plans or those of the Circle of the Black Thorn which, combined with Cordy's information from "You're Welcome," made it imperative that Angel had no choice but to act immediately in order to stop them. (His actual reason in "Not Fade Away" was nothing more than a suicidal gesture which, ultimately, didn't accomplish anything except the disaster that we saw in IDW's "After The Fall" arc)
On "Buffy," absolutely the worst episode of the entire series was "As You Were," because of all of the various convenient coincidences and unexplained things that happened, beginning with, "How did Riley know that Buffy was working at the Double Meat Palace if he hadn't called or talked to Dawn or any of the Scoobies beforehand?", and ending with, "Why, if Spike actually WAS the mysterious Doctor, were there no repercussions later from his supposed customers?" The kind of people who would be involved in that sort of business transaction wouldn't take, "Some overgrown Army boy scout showed up at the exact moment when the little bugs were hatching and fragged the whole cave. Sorry about that. Try me again in a couple of months, I may have something for you by then," as any sort of excuse. They would have had very specific plans for the infant Suvolte demons, and would be wanting revenge on the dealer who had screwed those plans up by not delivering on their deal.
