If you just can't get enough of the Dune universe, this might suffice. Based off of what we know from the first two films, the premise of Dune Prophecy SHOULD be quite interesting. However, it falls flat with a clunky storyline that only shows how incredible Frank Herbert's (as well as Denis Villeneuve's) vision was.
There are times when it feels intriguing but those moments are swiftly ended by the poorly designed set and costumes. Like could we please put some jewelry on the Empress? And what about the Harkonnen planet—were those recycled Wildling coats? I suppose most of the budget went towards the CGI, which, actually was pretty okay. I wouldn't say the acting was great either.
All in all, I wouldn't recommend this but I also wouldn't NOT recommend this. Like I said, if you just want to consume anything Dune related, you'll be fine. I personally found it goofy, boring, and messy.
