My 10/10 anime:
Tengen Toppa Gurren Lagann
If you haven't seen this, your life is not quite complete yet. ;o This series has tons of admirable characters and lots of energy. It just grabbed me in and I enjoyed it thoroughly. I like the soundtracks
Sorairo Days and
Row Row Fight the Power too.
Code Geass
When this was airing, I was waking up early, like, 7 AM in the morning to see the episode discussion a few hours after it aired. Then I spammed the refresh button until someone uploaded subs. Code Geass is a compelling and spectacular anime. I've rewatched episodes several times because I appreciate clever storytelling and plot twists. I can't get this anime out of my head.
