In new adaptation Yueh's betrayal came out of the left field without real explanation, wasn't shown how it was motivated, suspicions of everyone vs Jessica and Leto's trust in her are all dropped, and on top of it all Yueh's death was very anticlimactic compared to the old movie.
And also, Paul's awakening was my favourite scene in Lynch's Dune, and it was a letdown in Villeneuve's.
