The entire idea of the screenplay is very weak

Rating: 6/10 (11 September 2019)

I don't know if the book has the same type of story but I'll just ignore that and only talk about the movie.
The premise of this film was awesome: A group of ex-friends come together 27 years after they first met "Pennywise" to finally kill that clown.
But: What happens is this: A group of ex-friends come together to then split up and go on a solo mission to remember what happened in the first film because they've magically lost their memory of it. Oh, and then they kill that clown.
The entire movie was a wasted opportunity. Instead of giving us a new story, they give us a few jump-scares combined with revelling in memories. And the big problem is: There are WAY too many characters to do that. The film gives us atleast 5 minute segments of "I-need-to-find-this-metaphorical-artifact-and-regain-my-future" for each and every character (except Mike), which are all basically the same. The character remembers something, then a jumpscare, more remembering and another jumpscare. But as a viewer, after the first one, you know that absolutely nothing is gonna happen, because to them.
And then there is this whole "We-need-to-do-this-magical-ritual-to-capture-Pennywise-in-this-box" thing. When I saw this I thought: "Oh know, that's so stupid and doesn't go along witg the tone of the movies at all." And then near the end we find out, that its been a lie, and I was relieved... only to realize that this stupid ritual thing nearly ruined half the movie for me because they kept talking about it and I kept thinking that its absolutely stupid.
There's one thing I didn't really get: Was the ritual thing real magic, but it just didn't work? (Cause Billie had the visions and all)... whatever, who cares? After all, it had nothing to do with how they eventually defeat him.
Whiiiich brings me to the greatest negatives of all: The ending/the defeat of the clown.
They defeat him by calling him weak and scared and small and a clown? Really? That's some outburst of creativity right there. It's one of the most stupid, half predictable (because we saw glimpses of this in the first movie), and anticlimactic ways to end a movie like this. Horrible.
It's funny how they keep making jokes about how Billy's books endings are so bad, when the really bad ending is the one of the movie itsself.
Now, there are positive things to say about this movie:

the production value is great
the movie is (for the most part) quite engertaining
the dialogue is really funny at times (which is good, cause it has to compensate for the fact that the movie isn't scary AT ALL)
the acting is quite fabulous
vfx, music and cinematography are top notch

That's it, had to say this :D If you came this far, thanks for reading.
PS: the movie was worth the 4euroes I paid for the ticket!
