Critics typically aren't given screener copies of a new movie. What usually happens is that a week or so before the release the critics are invited to special screenings in a screening room somewhere, with security and studio marketing people in attendance. In a big city, they might do two screenings to get as many critics in as possible. Then they have a few days to write their reviews before they're published on the same Friday that the movie's released.
For the studio, showing this kind of movie to critics has no upside. You can bet that they're going to hate it just for being a big, dumb, loud action movie, and there's a good chance that the movie isn't going to do very well. What they can hope for is a big opening weekened, especially on Friday before any word of mouth can get around. Reviews will only dilute the Friday numbers.
Sounds like Transformers 2.
And Laz... I don’t know how they’re hanging from a roof. I live in a villa. They’d have to get past the Rottweiler’s first.
