In the beginning the show is honestly very repetitive, it's just pennywise scaring the kids in various ways, even though it's not boring, it's not that entertaing. However the last few episodes are so good, we get a lot of info on his background, what he is and why he stays in derry. Probably my favorite part of this whole show is the background designs, there is a lot of little callbacks from previous episodes and the original films, all of it just ties up so well while looking really good. After finishing the show I went on youtube and had to watch some videos explaining the ending cause I was a little confused and I ended up learning a lot about the Stephen King universe and how this ties up to some of his other works (like the Dick Halloran from the shining is the same as this one! I just thought the name was a fun little callback), anyways, this just solidified how gread this whole story is.
