Maybe it's because I don't watch Adult Swim anymore, but it sure seems like many of the AS comedy originals (especially the live action ones) come out of nowhere, have their run (often a very short run), and then stop. No wonder it's hard to muster up any kind of enthusiasm for them. At least anime has the built-in advantage of generating hype before it airs.
And let's not underestimate the "live action sucks!" viewpoint. Remember when CN began showing live action movies/series about seven years ago? I think there's still some of that attitude when it comes to the live action AS originals- "It's live action, which I don't feel belongs on the block, therefore I'm not going to watch or comment." That could explain why some of the AS originals don't get very many replies.
"Ah, crusty pants, a filthy wall, good morning!"
