Lynch makes the mistake of liking Paul too much. He didn't think about his overall arc through the series. For all Villeneuve's many faults as a director and the way he handled the source material he's left it open that Chalamet's Paul could be both a "hero" and a monster on his way to redemption far easier than McLachlan's.

The idea for example that the "Nuremberg-esque" scenes to come are a callback to the one from Dune 1 is exciting.
