“Wondering why some game reviewers are idiots. Newspapers don’t review movies based on a script. Why review a module without playing it?”I left the name off because that's not important for what I'm about to say. I'm not going to say what other people are saying. I'm going to say what I haven't heard anyone say yet.
You should not base a review of a game or adventure on actual play.
You are not reviewing a play session or a play group. Actual play gets reviewed in actual play posts. The game is not the session. GMs can modify rules and adventures, even unconsciously; players will adapt themselves to what other players are doing. This makes actual play worthless for reviewing a product.
It's true that you review a movie after you watch it. That's because the movie is the product. For games and adventures, the printed text, graphics and maps are the product. You review that.
You'd think that would be obvious.
