I agree with the first part. About the second I think is too high. The first Conjuring is at 86% and It 83% so the 91% you're predicting is a bit too high. I would expect it around 70%-75%.
I am not but American but I have to comment since it now became a big controversy.
The movie leaving out the flag planting moment is laughable and not in a good way. Who cares about historical accuracy nowadays?...
last Thursday and still no reviews? That's wrong.
Based on IT that was released on the same weekend last year (and basically this is the case for most WB movies) I would expect the embargo to lift tomorrow.
I think they are going to release one more trailer, probably next week.
The first trailer they released is described as teaser trailer in the title so... I haven't seen a movie with only one trailer.
