I'm not sure about that whole "too long" thing, we saw 'Once Upon A Time In Hollywood' a few weeks ago and I enjoyed the story. I've never been a particular fan of Brad Pitt or that DiCaprio kid but thought they really embodied their characters. I liked it.
Saw 'The Irishman' yesterday and agree that it seems just like every other gangster movie Scorsese has ever done with pretty much the same cast. I did think Joe Pesci provided an extremely low key and nuanced performance but Pacino and DeNiro were just playing themselves in gawdawful makeup. Overall I wasn't impressed.
