Really good watch, might watch again, and can recommend.
Asa Butterfield, Chloe Grace-Moretz, Ben Kingsley, and Sacha Baron Cohen all give a great performance in this weird, weird setting of an alt history train station, or hell, maybe this is a true story and I'm just that unfamiliar with the birth of cinema.
There is a great message of love and togetherness in this, but it's told in such an odd way. It's very refreshing, but a family movie from the point of view of an orphan is untraditional, and then there is all this theming of mechanics and along with weird dreams. Despite all the artsy fartsy nonsense, the experience and story are both fun and charming.
As long as you have an open mind, I'm sure this will be a fun watch.
