I just finished collecting there series because I remember loving them back in elementary school. I too, was hoping to reread and I had heard others say that they're perfect for enjoying as a kid and an adult, but OP isn't wrong that there's a clear formula. I'm only hoping that since I always knew the formula was the same, ie new adult, bad situation kids have to think out of, etc, that I won't be disappointed rereading them but who knows. I'm a little nervous now tbh
