It's not "good" and most of the "battles" are lame, but it's funny in most of its faults and occasionally very evocative in a way I can't imagine a modern action movie being.
I did laugh out loud at the lengthy worldbuilding exposition getting impatiently interrupted by someone else who wanted to do other worldvuilding exposition. Really 95% of the movie is exposition, and that's because 5% of it is lengthy establishing shots and the like. Normally I hate endless Proper Nouns, but it works here because most of it is casual and, hilariously, a lot of it is mentioned once and never again. That impatient interjection I mentioned name drops the "CHOAM Corporation" I guess that's something in the books because it doesn't seem to be here!
It was also a really bad idea to have Marty McFly demonstrate his combat prowess while refracted through a Roblox beta asset. They only use that shit one time later and it's in a very inconsequential way!
The TV miniseries is also really weird and neat, like they did NOT have the budget for a sci-fi setting like Dune, but I actually enjoyed it a lot. The costuming can be kind of weird at times, but I will go to bat for the Landsknecht Sardaukar, I read a lot of people complained about the costumes when it came out but a medieval/early-modern inspired vibe actually totally fits a space feudalism setting.
and look at these weirdos
