I grew up reading the books as they came out, and where I had read (or had my mom read to me when I was too young to read them myself) the first 3 books repeatedly, I definitely aged out by the time 6&7 were released. I think I read 6 once and I couldn’t even finish 7.

I also noped out of the films after the spider in 2 (holy crap I was way too young to be seeing that film btw!)
