This is a stunning film, both visually and in its scope. Tonally, it reminded me a bit of 2001, and I suspect that it might become a future classic like that film. All the actors do a great job, and there are some deeply affecting moments that stick in your mind.
Sure, it drags a little bit at the start. Yes, there are one or two dodgy plot points. But for me, that didn’t decrease my enjoyment of the film and my engagement with it.
