The thing is, when we have so many high quality TLJ edits available already, which improve the film narratively (like you say) just as much or even more so than Ivan’s, his edit had to be at least just as good from a technical perspective, especially with all his claims of being a professional editor and all the hype he built around his edit. But no. It brought almost nothing new to the table while also being quite a failure from a technical standpoint. So while it may have been enough for his followers, it certainly wasn’t enough for us, who have stuff as well made as poppasketti’s or ForceGhostRecon’s TLJs, for instance.
There’s also the fact that Ivan monetized his videos where he worked on the edit - publicly utilizing an IP not owned by him to profit, thus endangering the entire fanedit community, among other offenses, such as using pirated material, which gave him a really bad reputation around these parts.
