Wolfs Rain is pretty bad. It's great looking and sounding, but the story was almost FFXIII toriyama bad. One of my least favorite Bones though I recognize it for the artistic merit.
SAC & 2nd Gig are awesome. Should go somewhere on that.
Gurren should be somewhere in a top10-20 because the first half is the best Super Robot show since Giant Robo. Well directed, stylish, great comedy and action. The 2nd half is weak, but the first half is strong enough to get it on a list.
And E7 is amazing, only weakness is that they cut their budget because the show was bombing so ep28-the last 3-4 eps are really cheap looking. E7 has such a good story, original cast, great direction, great art & music; just amazingly epic show that's rarely made.
