Major Plot Hole (SPOILERS!)
So we all know the girl was dead the whole time (at the end) and that he was interacting with her ghost....
But, when he sees ghost they remain in the form they were in when they were killed right? Guy with missing arm is wearing the same clothes and still has an amputated arm.
But Stormy'/ ghost constantly changes outfits. Surely this is breaking the rules to promote the whole "she's still alive" angle.
Either way, it's a minor criticism. Love the film and love/d Anton Yelchin.
