I've watched it loooooads of times already and it's just perfect! I'm turning 15 now but I first watched it when I was 12 and I can say that teenagers and pre-teens all act exactly like that! Even though it's a horror movie, the humor is on point and you end up laughing at the same jokes every time, and also that makes you forget about the horror part of the thing. There are a few jump scares (most of them are on the trailer though) but aside that there is not much horror horror, ya know? Only there are a lot of gooey scenes so just a warning if you don't like that kind of stuff. The casting it's also soooo good, and it's so fun to watch their relationship off camera being almost the same as them as the Losers. The directors and producers did an amazingly good job too, making perfect takes for important scenes and really convincing special effects. Yesterday I re watched It 2 and it's also perfect, I'm a huge fan of both movies. Definitely on my top 7 (don't ask why 7) favorite movies list and definitely a must watch movie!!
