Adam's nothingness is what strikes me . . . he's so neutral & clinical until the final 2 eps. (It's as if for AtS4 they looked back & said "Adam scared nobody so let's build a superscary Beast". . . ) Demon Forrest, on the other hand, was truly nasty. A de-personalized villain isn't a good villain, tho', and it'd've been much more interesting to investigate Maggie's motivations. . .
