I think the biggest fallacy regarding Movie World is that they somehow need to tie their attractions to big film releases to stay relevant. Let's face it, it's a theme park not a museum, being relevant to cultural phenomena is secondary (generously speaking) to actually having a good ride experience. Wild West Falls being the truest indicator of this, a legendary ride originally (tenuously) themed to a flopbuster and thereafter renamed to possibly the most generic of theme park staples, and yet I don't here anyone frantically calling for it to be tied to whatever flavour of the month multiplex monstrosity that's raking in the big bucks.
tl;dr, HWSD doesn't need to be Mad Max themed or whatever, it just needs to be good and fun and funny. Like, seriously just make it Police Academy again, who the f cares if it's not relevant as a movie franchise. Last time I checked people were still watching and enjoying the damn thing.
stl;sdr; good ride/attractions >good theme/good movie tie-in.
