I agree, it was ground breaking, but, was it the greatest anime of all time, no, far from it. There is a lot more better produced shows out there than this one, IMO. I just got tired of all the emo crying from the main character, it was annoying and the 4 minute pauses of doing nothing but hearing power lines. No, thank you. If I want a thought provoking series, take Serial Experiment Lain for example, despite it had it's 4 min wait time too.
Some of the better produced series, in no order:
1) Seirei no Moribito
2) Eden of the East
3) FLCL
4) Dennou Coil
That's just to name a few!
