Not much works here. Big miss.

Rating: 4/10 (3 December 2019)

The 10 star ratings and gushing reviews are a joke. They cannot be serious; they are not credible. The blind loyalty is hard to fathom.
The script itself is boring. A snoozer. Time creeps by so slowly that you not only look at your watch, you shake it too to make sure its still working.
JUST BECAUSE THIS TEAM MADE GOOD FILMS IN THE PAST DOESN'T AUTOMATICALLY MAKE THIS A GOOD FILM.
Yeah, Pacino, Pesci, DeNiro, Scorsese -- a legendary combo. No one denies this. But this film is garbage: Scenes that don't advance the plot. Half-hearted acting. Drab dialogue. Thought experiment -- replace the main actors with unknowns. What would you give this title then? 10 stars? Best film of the decade? A masterpiece? Lol! This wouldn't make it out of 2 star range.
And here's the thing: Aside from Pesci (who holds this film together with an amazing turn) the acting is average. That's a fact. And a fact that is noted in other reviews here grounded in reality.
And the absolute worst thing about this film-- as noted in other reviews -- is that the de-aging simply does not work. IT. DOES. NOT. WORK. AT ALL! This leads to bizarre, jolting scenes that rip you out of the story and have you looking at people around you like "WTF???".
The grocer scene comes to mind. A 100 year old DeNiro, de-aged to (something? Its hard to tell, he looks like a Sleestack from Land of the Lost) beating up on a grocer that outweighs him by a 100 pounds is comical and strange to behold. DeNiro hits about as hard as a 2 year old boy fighting for his favorite dinosaur. Scorsese would have done better to have young DeNiro TOTALLY rendered in CGI like the Hulk. Seriously.
Get a grip in reality 10 star people.
