so i read almost all digitally because i have a limited budget and limited shelf space, so i only buy books i know i'm going to reread. i've recently decided to slowly start buying one of my fav series to have on hand to reread, but this is a bit of a special case in regards to this question. normally you would think "yes obviously you should buy all the books or you're going to miss out on the story when you reread in the future and forget what happens" but the series i'm talking about is interconnected but standalone romances. there is a wider connecting plot, but they all focus on one couple and their story with crumbs of the overarching plot weaved in. this series (or this part of the series, it's part of a larger universe) has 9 books currently out and there is definitely one, if not maybe a few more, that didn't grip me as much. i don't hate them, but i can't think of rereading them for the couple since that's the main part of the book. would it be weird to just buy the books i know i'm going to want to reread and just leave gaps for books i didn't like as much? or should i just get all of the books to have a complete set?
