I agree with Zocano.
Part 2's ending is a series of absurd escalation, from Ultimate Kars, to Joseph flying away, to PIRANHAS, to Stroheim out of nowhere, and then...it relaxes the pace for a moment when it seems Kars was defeated, before going back in with Kars cutting off Joseph's aim, pulling out super hamon, and then being blasted off into space, all while SONO CHI NO SADAME plays.
Part 3 has the same structure, when Dio and Jotaro fight, pulling out time stop, knives, Polnareff, flight, tricks, power up with Joseph, and then ROAD ROLLA DA, when it relaxes by Jotaro cornering Dio. That's followed up with...Dio blinding Jotaro with blood and Star Platinum breaking The World with a knee punch.
It makes sense, sure, but narratively it's unsatisfying. It's low-key when it shouldn't have been.
