I think he’s obviously capable of excellence. Most of his films in the 70s are indicative of that. After he was offscreen for a while in the 80s, he returned with another very good performance in the effective thriller Sea of Love.
Post-Sea of Love is where we get a lot more of raspy-voiced, yelling at the top of his lungs, over-the-top Pacino but there are still some fun performances from that version.
Plus, I think he’s great in Donnie Brasco which is during that more over the top era but is actually a quite subtle, nuanced performance. Same goes for the Insider, one of his best post-Heat films and an excellent performance.
