You make a very valid point about Kimchi's version's lack of bonus items. That came as a bit of a shock to me and made me think maybe they just rushed that aspect of the release. The lenticular came out great though, if you don't mind the same overused art that the amaray versions all have.
As far as the Manta release goes, again, same overused art, but while I agree that it can seem like a "two-in-one" movie style artwork, to me, it symbolizes the light versus the dark. The good Peculiars versus the evil ones. I like that dichotomy and it was bold of Manta Lab to do something like that. It sets this release apart from some of their other Global efforts (the extremely dull Legend of Tarzan release comes to mind). And it makes for a dynamic lenticular, way more interesting imo than the Kimchi one.
But FA's slip choice is really interesting and, if the finish is right, it very well could be the most beautiful version and certainly one of their greatest efforts right up there with Everest, Looper, and the like.
