I remember watching that on Adult Swim. That was one of the more odd, yet intriguing shows I have watched.
It seems that you are making anime out to be the medium of which Japan makes shows in general as if they have few good actors or writers so they rely on animation instead (whether this is true or not, I don't know, but it seems that way.) I suppose in some cases it can allow you to be more creative, but it is also kind of a cop out. Granted, the styles of anime don't seem to vary nearly as much as the styles in domestic animation. I'll say anime has come quite a long way...the quality started out as absolute garbage...just look at speed racer. Or hell, even Pokemon today. There are goods and bads to every style of animation.
A lot of classic animation styles were fantastic. While the character models seemed simple in some cases, body movements and expressions were very thorough, and many of the backgrounds were very detailed. You may (or may not) be surprised how highly regarded classics are...Hell, even The Peanuts...They were one of the most highly regarded, especially for their use of expressions.
I do think a lot of today's cartoon's are crummy, anime, american, what have you...I also noticed some shows did poor anime spinoffs, or there was a trend towards anime based on "americanized" themes, such as "batman beyond" I think it was, or that Teen Titans show.
One of my favorite cartoons was no doubt the Batman animated series made in the 90's.
Oh, and I just have to bring up Shin Chan. Funniest cartoon I have ever watched, but the animation is the most atrocious. I think that adds to the humor though.
