EDIT 10/27/18:
But I've been warned about the visuals in this movie, thanks to the Disability community on Tumblr, so I'm waiting until I can watch it streaming on my computer -- a smaller screen, in a brightly lit room, where I turn off the screen, if I have to, and just listen to the dialog during the worst of it.
That should help, but it won't substitute for a genuine description track. A lot happens in the visuals that is not audible, but based on comic book tropes, such as thought bubbles.
