I am sure you know of the new remake of the film coming soon, then. It will be interesting to see in comparison to the book/original movie from the 80s.
I am aware of the remake and I wonder if those whom remember the mini series will see it negatively because of a sentimental attachment to Tim Currys portrayal of Pennywise rather than any issues with the material its self.
I reserve judgment as well because at the end of the day if I don't like it I'll always have the original or the version I watched in the case of series like the mummy which have mutliple remakes.
