This episode falls apart in nearly every way possible. The characters overreact to everything. The final revelation is anything but surprising, and yet, once we know it, nothing we've seen before makes any sense. Some mysterious characters' motivations are never explained. In short, the entire script plays out like a poorly conceived "gotcha" that strains credulity at every turn. You persevere to the end hoping that at least the explanation will offer something of a payoff, but everything just crumbles like dry mud.
Nor does the direction help in the least. The characters are either annoying or unlikable. Humorous moments are thrown in with no rhyme or reason. We cut to commercial seemingly every three minutes. And worst of all, THERE'S NO FEAR! There have been some entertaining entries in the series, but this is not one of them. It feels like a student film based on a high-schooler's screenplay. Skip it.
