Well there haven't been screenings in Europe yet.. And most of all, if you take a look, on Facebook is FULL of people commenting they want to see it, there are loads of excited comments of people who can't wait to see it.
Btw I asked around cos I was curious about this screenings thing and people told me it's completely normal, I mean it happens very often. It won't affect the box office, the screenings are few compared to all the people who want to see the movie. + no screenings in Europe / Asia yet.
Screenings are not that relevant to affect a movie's box office. If they affected it they wouldn't be so many.
It's a good thing to see people's reactions and to have the first predictions/reviews.
It's normal.
