I agree you have to filter a lot of crap to get to decent stuff. There are a couple series I really enjoy, but most I take a pass on. I also remember Robotech as a kid and being amazed at the quality of animation, but now when I go back I realize that some of it just looks terrible.
Oh well. I just keep my eyes and ears open for new stuff I might like. Every once in a blue moon something good comes along...
