How are people giving this horrible ratings?
It's not even out yet. Shouldn't people who vote on movies they haven't seen based on prejudice have their membership revoked?
Many movies are released to select audiences BEFORE the official release to the general public. For example, at screenings for critics and at festivals all over the world. Not to mention that different countries have different release dates and on the very day you posted this message the film was released in Germany. Not everything is a conspiracy.
Aside from that, on IMDB is says right next to the rating "(voting begins after release)" so it has to have been released SOMEWHERE to allow voting.
