There were 2 cool statue effects... the one I noticed right away because it was recycled from Nightmare On Elm Street from 2010. I took a pic of it LAST year:
They also recycled the effect of the hands that push through the walls.
And I almost forgot about the stilt walkers! Seemed like every maze had 2 of them
They've actually recycled a number of things. Alice is half Nightmare, if you ask me. But I can see why they'd do it.
