I also really liked how the Krayt dragon seemed to almost magically pop up from both the sand and even solid rock at some point. It’s the kind of fantasy monster logic I expect (or at least prefer) from SW, even though it would have been quite jarring in a ‘proper’ sci-fi series/movie.
Also, did the new version have legs or did they just straight up turn it into a worm? I know most EU versions, both new and old canon had legs, but the skeleton in ANH seemed to just be a spine and a head so I supposed making it a worm of sorts works as well.
