It's like being forced to stare at a beautiful painting for 2 hours.

I would probably say that every second was enjoyable and engaging at many points, but in of the actual plot, I felt like there should have just been something more. I don't know if I missed something. After checking the reviews, I am confident I understood the message, but actually watching the film, especially the third act, felt like it should have had something grander, as that is what it felt like it was building to.
It is still an excellent movie, but I think my anticipation was just a little too high for my own good.
