What's a show you thought you'd outgrown, but ended up still loving?

Even in my 20's, I still love Sword Art Online. The 1st time I watched it, I was in middle school and I enjoyed it. 10 yrs later after 5 rewatches, I still have a soft spot for the series. When it came out, both the weebs & Anitubers were making shots at it and calling it the definition of "Isekai trash". But after rewatching it and making a review for each arc, it really wasn't that. There's effort put into it, which is more than I can say for most anime nowadays. It just represents what I'm looking for personally; a story with an interesting hook, characters I can personally get invested in, and world building that keeps me immersed. That's all I'm looking for in whatever I watch. Even if this subreddit hate this show's guts, it's still a good series to me, after all these years; especially with a masterpiece like Ordinal Scale
