Anime series' are pretty damn interesting. That's not a comment in reference to the content within, but instead, how long shows run. Some anime series' only go on for a couple of seasons, while others seem to have no end in sight. It surprises me that there's no real middle ground with anime when it comes to length. You either run the show into the ground or end when fans are just dying for more.
Take a look at the Bleach series, for example. That's one long-running anime series, and who knows when it's going to end? It seems to just keep pushing forward with no end in sight. Is that a good or a bad thing? That's not for me to decide, simply because I don't watch the show. I could offer up an opinion if I did, but that wouldn't be the end-all, be-all of the series' future.
Now look at Cowboy Bebop. That's another highly-regarded anime series, but it ended after just a short amount of episodes. The series we got was action packed and top-notch, but we all would have loved a bit more along the way. There's something to be said for having a short-but-long-lasting legacy. Cowboy Bebop said what it needed to say, and in just a handful of episodes.
Which would you rather have with your anime? Would you like to see short series' continue on until all popularity drops off? Do you wish long-running shows would cut it short? It all depends on the quality...but would you be willing to take that risk? Dare you push for season after season, knowing the quality could disappear at any moment?
