The whole cast was awesome in this, but especially Bardem, who had couple of good comedic moments that really worked for the audience. Shouty Timothee also really worked, though I can totally see Clay's point about the transition being too abrupt. I think the change of Chani being a skeptic helps here though, as there's a palpable dread hanging over everything. It's a tad alienating to lose Paul's perspective at this point, but that might also be the point as well.
Beyond curious what approach Denis would take with Messiah at this point. Please, please let it happen.
