5 stars because the very very end had me crying. I didn't expect that and almost cut it off before really ending. From the early part of film three things became quickly clear: Israel was brilliant, autistic and living in the past. We had to hold our breath for everything else. I usually pause movies and go back later but had to just make some popcorn and watch this one till finished because it was so engrossing. Denzel, Colin were great, as well as the social activist and the potty mouthed student.
