I saw it yesterday evening and I think it's a great movie! At the beginning it may seem "strange" and it may bother because of all that moving but then it's fine, I think.
Anyway I expect a quite different ending:
Spoiler:
the happy scene that shows them on the wheel, having fun



it's not what I expected. I thought
Spoiler:
we would be given an explanation of the monster at the end.



However, great movie!
