In season 4 we have ripoffs from

IT - Part 1 and 2, because its just the easy way to do it and due to lack of imagination from the writers, so just ripoff stephen Kings plot and story.

The season so far is a big mess and the different story lines fit like a size 8 foot in a size 4 shoe... its bad in so many ways, that the writing of this season damag the series.

Overall its just very disappointing and a dull ending to a great show :(
