Critic Consensus: "Filter" continues Castle Rock's slow burn, drawing viewers deeper into the terror of the unknown while building toward some shocking answers -- all without offering much in the way of movement in the overall plot.
Critic reviews for Filter
Filter doesn't quite emphasize on the stir from last episode, but it's a bridge to what I'm hoping will be ideally nefarious.
Though "Filter" concludes on a rather grim note... it's hard not to be utterly thrilled with the possibilities the revelations in this episode have opened up.
Filter, for better or worse, stands right on that precipice of providing answers and overpowering the rest of the show, like a bad ingredient in a recipe.
Well, that cliffhanger can go straight to hell, which is coincidentally what awaits the people who caged the Kid for all those years.
"Filter" does not offer any clarity but continues to advance the story forward in a terrifying manner.
