Gimme a sec; I gotta process all this...
First, SHOCKER, it's actually really dang good! (All the more shocking since it's a prequel to 2014's Ouija, similarly produced by [audible gasp here] Michael Bay!) The 1967 setting is delightfully nostalgic, reminiscent of The Conjuring 2. Retro 'Universal Picture' opening credits and everything.
Second, and here comes the spoiler (!), if you stay past the credits...you'll find Lin Shaye sitting in a wheelchair, again, staring out the window, again. For a moment, my mind exploded, because I thought she was Elise Rainier, tying together Insidious and Ouija universes in some mondo crossover, the equivalent of Batman battling Ant-man, but alas, she's just l'il ol' Lina Zander.
Duh. Of course she is.
Anyhoo, I enjoyed having my mind blown, even if it was only because I got confused for a minute there.
I'm getting real easy that way, like old men who argue with themselves while playing solitaire, or dogs that run themselves silly chasing laser dots across the carpet.
