Saw this the other day going in without expectations since the original is one of my favorite movies.
I actually liked how they tweaked the original story to keep the mystery from 1987 fans and kept it fresh by introducing some new ideas to develop on. It was also fun to see the nods to the original as well.
I think if you go in without comparing it to the original (which is hard) you might be pleasantly surprised. Pacing felt brisk despite the 121 min run time and that is saying a lot because I can hardly sit through many of the 90 min movies made these days.
