To make a long story short(and my night of personal report was HELLA long)-Anime Expo 2010 converted me to Gurren Lagann. To be honest, I at first thought it was rather over hyped and not deserving. But all the fan enthusiasm at the movies, plus meeting Konishi-san(ANIKI) and seeing his love of this wonderful anime made it so that I was onboard right after. RL Aniki inspired me just like Kamina inspires Simon <3 < /cheese> I just finished today!(so I thought it was safe to join/no spoiler potential anymore).
I read that intro posts must include offerings, so please go to these links at my LJ to read a report on Konishi-san's panel/the TTGL event, plus a few pics from the seiyuu events I attended. (Morita Masakazu-san and of course, Aniki's)
ETA: the pictures are generally of horrid quality, apologies D:
