Looking back on old fandom fics is difficult for me now because it's obvious how OOC every single character was in modern AUs. The BC fandom at least has the most basic characteristics of the mains down (for the most part). I feel like a lot of the fics I used to read would be really cringe-worthy now (for other fandoms).
There were definitely a select few that still stick with me, though, and I'd love to re-read.
