It is easy to tell that Pet might prove to be a bit much for some people. It certainly doesn’t appear to be an anime that you’ll want to watch if your aim is to relax.
For many people anime is just a form of entertainment, just another medium that helps pass the time. For others anime is much, much more than that.
Good anime series require a lot of work, lots and lots of daydreaming / fantasizing and a bucket-load of care and love…
It was quite a let down that Pet didn’t air last season. But as soon as I saw its poster, a certain prog rock sound came to mind.
