I don't know whats up lately, but I find myself enjoying Romance, Cooking, and Music anime more than the Action stuff lately.. maybe its me getting old?
More than likely just a mood thing, we as humans always go through mood changes whether it be due to the seasons or something triggered in your mind that has changed what your interested in atm. Doesn't mean you dislike action or won't get back into it hard core 6 months from now. I am different since I watch every type of genre I go from either, playing very little games and watching a lot of anime, to watching very little anime and playing a ton of games. No matter how good the series or season and voice actors there are times when I just drop them all and play games non stop for a month lol
