Maybe it's my fault for not keeping up or something, but I have no idea who Elena is.
Coco is quickly becoming a beloved film that celebrates a culture rarely represented by Disney, has decent songs, and a heartwarming (albeit cliche, and very reminiscent of Pixar's previous work) story. It has incredibly unique and detailed environments that would translate really well into a dark ride environment. I'd actually be excited to see Disney build a Coco attraction, just to see that world brought to life- since a ride would be free of the limited storytelling the film offered.
Once again, I have no idea who Elena is, but I doubt whatever she is in is of the quality that coco is, and would be surprised if whatever she was in was more attraction worthy than Coco.
