Don't understand the big fuzz about this movie

Rating: 7/10 (11 March 2018)

I have seen a lot of movies with finer acting and better storyline. I don't understand what's the big deal is about this movie, that everyone is so crazy about it. In truth, I find it a very stupid and illogical ending with the doctor not shaking hands with D Caprio and then this whole nonsense shooting came. The Dr was all cool throughout the movie but right when the man was about to get his wife, he had to open fire. Wow Who wrote this? A six year old?
