I'm asking if we should trust all statements claiming to come from the critics, not about the films themselves.
The claim is in every TV add for the film on DVD/Blu-Ray.
Just turn on the TV and watch the commercials, you'll see and hear it.
I saw the commercial you're talking about. Individual critics aren't named, and on rotten tomatoes I can't find any critic saying what the commercial claims (your word as well) is saying.
It's one thing to say "Critics are saying this." It's another to point them and their words out with easy proof. For example, First Class.
Strange that one would use Transformers as an example to discredit the critics when, when you actually look at what the critics say, they're saying the opposite of the commercial.
