The first hour of The Irishman is the worst part of the movie. The writing is crammed in the beginning, and it does not give a ton of room for the characters to breathe. Also, the limits of the de-aging technology are on full display during the first hour. There is one scene where Robert De Niro beats up a guy in a shop, and it looks very silly. Even though his face is younger his body is not the age that he is supposed to be in the film, and so it looks strange. It is also unclear what age the characters are supposed to be at what points. De-aging technology needs work but after the first hour, it disappears into the film.
The film really becomes great in the last hour. Then after two in a half hours, the film’s themes of age and loss come together in a searing finish. It is a devastating end, and the length in some ways helps the impact as you feel you have been with these characters for so long before it all comes together. I won’t spoil anything, but it is definitely worth it if you are willing to watch the movie.
Robert De Niro is a standout as is Joe Pesci, but Al Pacino is the showstopper as Jimmy Hoffa. He energizes the movie and brings out the emotional core of the movie at many points.
If you are willing to sit through three and a half hours this movie is worth it. However, make sure you know what you are in for. It is long and takes time. It is flawed and needs work in certain areas. If you love Scorsese however, this is a must-see. I think the flaws mostly in the beginning hold the ending back for me, but it is so brilliant and searing, the movie just gets into the A category. A-
