Every one of the twelve reviews lands on the positive side, and most of them say the same two things. First, Colin Firth’s Michael Peterson is the reason to watch: critics return again and again to how slippery he makes the man, insecure and evasive at once, with Toni Collette nearly as often singled out beside him. Second, the series earns its place next to the documentary it retells by folding that documentary’s crew into the story, so it becomes as much about how a case gets narrated as about who did what on the stairs.
The spread is narrow. Nobody thinks it fails; the question is how much it adds. The Evening Standard calls the dramatisation unnecessary even while admitting it grips, and The Hollywood Reporter finds the early episodes uneven. The AV Club, having seen only part of the run, holds back a final view until the ending. Collider is the warmest, treating the performances as reason enough.
