It was a very well made movie, BUT.......
We already knew the Main story.... so it wasn't really that good ----to me----
If you've never seen the original, you'll be happy leaving the cinema.
I've only seen the 89' version once or twice I think, it's always been one of the 'backburner' King stories for me, but I still remember all the iconic parts.
I purposely avoided watching the trailers and was actually pretty surprised by the 'twists', the rest of the movie still has a lot of issues however.
