100 minutes into the movie then you shockingly ask yourself, "How're they gonna wrap it up in the remaining run time?!!"
It was an excruciatingly long movie which didn't come to an end while you were expecting it to end in the 2nd part! Yes the visuals were fantastic the actors were great, I know it all, but it just faltered with its boring story and addition of other sides like Paul's ancestry, smuggler commander, unreasonable acceptance of prophecy by all "weak northerners", unimaginative introduction and characterization of Paul's psychotic causin and many other problems. It just let me down!
Further, the Emperor's so-called army and its commander were just too weak compared to the brutal army and its commander in Dune Part 1. There was not a single mention of the other houses throughout the movie except their refusal to award Paul's emperorship, the Emperor himself was just an imbecile!
