I mean honestly I've been reading this for SO many fucking years that I can tell you yes, the first seasons give me a lot of nostalgia. But also, the story was completely different, it was darker before, and now that the kingdom has more freedom than before they can chill out, yk? The story seems more relaxed. I know what you mean though, I also dislike the whole "now the story focuses on their child and their adventures yada yada" which is *very* used. Cough, cough-- InuYasha (,I will never forgive them), cough, Naruto, cough. I'll still read it of course, but it's okay to not enjoy it as much as you did before, sometimes it happens (/TДT)/
Nope, not at all lol I purchased all the chapters on Tappy, went back and reread the entire series from the beginning and it became even clearer just how much the quality drops off was once S3 starts. It felt like watching a great anime only to then watch low budget OVAs. So if you feel this way, it's not in your head and you're not being nostalgic. It's just not that great compared to the other two. But it's still worth some entertainment. As long as you go in with low expectations you'll be fine.
