Josiah Morgan’s review published on Letterboxd:
I've viewed pretty much the main body of Sergio Leone's work. Once Upon a Time in America is the best of them all. In my mind, now, I don't think any gangster film will ever top this. Including The Godfather. Also including The Godfather Part II.
At a four hour run time, you would expect to get restless... right? Wrong. The time just... passes.
Perfect in almost every way.
