i think it'll be ok but its budget is $165m which means its gonna have to make at least $400m ww to be considered profitable and there is zero chance of that happening. The movie won't even cover all of book 1.
it'll get stuck in that weird hell of it did ok enough to do more, but not so well that everyone wants to make another movie. And its been over 2 years now since the first movie wrapped production. At best I'm hoping it leads to yet another reboot in a few years of an HBO max or Netflix or Amazon Dune series, which wants to go deep into the rabbit hole.
the only real interesting question at this point is what cliffhanger does the movie end on - exile, spice awakening, shield wall, or something else?
