Other things:
All this talk of how they originally had Evil Dead 2 Necronomicon and references, only to switch them with 2013's... I can't help but think they wanted to tie things into a possible return for Ash, like how they wanted to do another Army Of Darkness and then another movie where Ash and Mia unite. (To those new here: Bruce did mention, during Rise's promotion, how he's open to coming back if Sam Raimi directed - maybe just pillow talk, but I believe him). But after Bruce's cancer diagnosis, they figured, 'Well, that's definitely not happening. Let's stick to the 2013 only and we could have the possibility of just Jane Levy meeting with survivors of Rise and Burn.' (Just what came to mind when learning about the book-switcheroo).
I like how Alice, when fighting deadites, heavy breathing and full of blood, looks just like Brandy Williams. Felt like I was watching a Brandy solo Evil Dead movie.
The Ellie post-credits feels lame. If Wrath doesn't come out for whatever reason (hey, it's Warner Bros., could be another tax-write-off movie), if Evil Dead Burn is the end of Evil Dead (and it is, for now), THAT's how we end things?
Whose ashes are in that urn? Ellie was put through a wood-chipper grinder thingy. She would just be blood. Did they actually scoop up the bloody puddle and burn it? So it would be Ellie and her two children (Danny & Bridget) united as one bloody puddle that was then burned somehow into ashes? Ellie appearing symbolizes the evil is not done tormenting Beth and Kassie (in my interpretation). It just feels wrong to put it in there because it's not an episode in a season of television, it's a movie, an ending. And there's nothing wrong with a little mystery to leave the audience with, but it felt too gimmicky (Marvel wannabe with same cliche music crescendo).
