A good anime show usually has several seasons; if an anime lasts long(er), it’s usually a good sign that it is a high quality show. Depending on whether it’s an original story or a manga adaptation, an anime will have two, three, or more seasons and will be on the air for years, even decades in some cases.

But, alongside these, there are those anime series that come and go. They do their run, usually between 12 and 26 episodes (although there are some notable exceptions) and they simply end.
