Crimson Peak is worth seeing purely on the grounds of its achievement as a work of art, because the second time around, it's very clear that this movie is rather pointless.

To explain, in spite of its tightly constructed narrative and elaborate production design, it never really goes anywhere. It can be fun, but rather predictable, for fans of Gothic romance, because it's very clear Guillermo del Toro understands all the tropes of Gothic romance, and while he cleverly implements and subverts a few of the aspects that embellish this limited genre, he never really succeeds (or even tries) to really subvert, nor does he really create a sense that he's paying homage to the Gothic literature he's obviously taken so much inspiration from. Instead, he's contented with recreating a somewhat familiar story that's been retreaded dozens of times since the dawn of Gothic literature in Castle of Otranto, but he does it with more artistic finesse than this genre has ever known in film.
Seriously, this is one of the most beautiful movies I've ever seen. The over-decorated and over-stylized sets are gorgeous to look at, the camera is constantly moving and constantly panning smoothly across the bellowing hallways of this haunted mansion, and the special effects are spectacular, it's just disappointing del Toro doesn't do much more with it.
Yes, the narrative is tightly constructed, and there's lots of structural details that are fun to pick out, but this movie has no conviction. It isn't a movie that's enamored with Gothic romance, nor is it a movie that tries to subvert the tropes of Gothic romance, nor is this movie much of an exercise in tension building, it's merely an artistically brilliant showcasing of Gothic decor and architecture that's strangely hollow.

As far as performances go, they're all fine. Mia Wasikowska is gorgeous as usual, and Tom Hiddleston is dripping in so much charm you'll be wishing you were the one he was trying to whisk away to live with him in his creepy mansion, but the one who really steals the show is Jessica Chastain. She is bursting at the seams with evil relish.

Overall, I thoroughly enjoyed myself. It's too bad this movie lost so much money, since that means we're not going to get anything else like it any time soon, which really bums me out, because everything about this movie is so exceedingly polished that I wish somebody could revisit it and truly bring out its potential.
