Sorry, what is FLCL?
I understand your point of view, but I think that watching anime or series in general while they're still on air has it's magic. Having to wait to see what happens next is something that I like very much. If it later becomes boring or something like that, I'll just drop it, but I'll have already enjoyed the beginning of the story.

I've outgrown this romantic approach :P. I work and when I come back, I have limited time - some for gaming, some for anime, and sometimes neither. I don't waste my time on titles that have a good beginning, development, and the final stage is plot no jutsu. The world offers too many series for me to watch the broken ones.
