Slow and confusing title

Rating: Null/10 (8 December 2019)

Sorry for being pragmatic but, why Robert De Niro, the typical American actor, to play the Irish man? Then, why 3 hours? I hadn´t seen that length since Titanic, which I could appreciate as there was action all the way through , but not here. I was attracted by the first scenes where I could see again some ageing actors and well-known director, but here is the problem: the same actors are supposed to play 30 years younger, except that they don´t look more than a couple of years younger, at best. Then, because the cast is ageing, all the ´action´ is slow. It may be fine for an ageing audience who will be happy to see their ageing stars but I am not this old yet. I am not rating this as I am not planning on watching it until the end, life is too short. No offence to the actors and the director which I appreciated elsewhere, but not here.
PS: Mr. De Niro, could you please stop doing this gimmick face that you caught on Taxi Driver? It was interesting back then but, time has passed.
