I imagine they must have just been clapping for Season 2 in general, since it was the season finale, because Shades of Gray is objectively the worst episode of Season 2, and I don't think there's anyone on this planet who would care to disagree on that. Yes, the one with Deanna having a space baby and the one with the Animorphs were both better. At least they were episodes of a goddamn television show instead of glorified clip shows.
Season 2 was a lot smoother than Season 1 but it still managed to trip over the finish line and eat dirt.
