I used to think the songs were fine but by season 2 I was finding them downright annoying. In general I really couldn't stand the series for the last couple seasons but stayed with it if I had nothing else to watch, which was rough and I regret bothering.
Movie reminded me why, though. I like watching shows with a live thread. Of course, they have to be shows I can stand so it's still a surprise in retrospect I only skipped a few episodes. Still going to watch it even though the trailer and what I've heard doesn't pull me in much and it just looks like an excuse for more anime "references". I just have jack shit to do anymore.
