Great cast + great director + great plot = Mediocre film
If you want to see 70+ year old men try to act like they are in their 30's this is the movie for you! While CGI was able to cover the age lines on their faces but their movement was completely rigid with lots of shoulder shrugs and head bobbing. Absolutely no swagger in any of their gait. It was obvious they were old men trying to act younger.
Make room for the new guys. DeNiro, Pacino, Pesci... They have made enough gangster movies. Give someone else a shot. They should have went with a crop of new talent and used CGI to age them. It is easier for a young man to act old than vice versa.
Also, Robert DeNiro plays the same character he has buttered his bread with for his entire career. But CGI blue eyes? Just not very convincing as an Irishman.
Based on other reviews I've read I am in the minority. But in all honesty, I barely made it through the entire movie. If you like movies like Goodfellas, Scarface and The Godfather go watch them instead.
