Irvin Malcolm’s review published on Letterboxd:
Allegedly based on a true story of Frank Sheeran, a war veteran recruited to become a hit man for an organized crime syndicate and becomes friends with Jimmy Hoffa. Director Martin Scorsese returns to a familiar well alongside Robert De Niro and Joe Pesci and bringing Al Pacino along. At first glance, this feels like familiar territory. We've already seen this from him. What more can he do with this? As it turns out, at least one last thing. This is a more introspective and nuanced gangster flick. It feels like a culmination of what his previous mob-related films were building towards. The film is three and a half hours but I felt it kind of had to be. Being with the characters a long time as we see their story unfold really gave the film a layer of poignancy and emotional resonance. Robert De Niro is excellent but Al Pacino and Joe Pesci were both great. Yes, it is indeed one of the best of this year's "real" cinema.
