SEED is my favorite. Yes, I've watched them all (except for Fighter G, couldn't make it 4 episodes) and I've heard all the arguments against it.

I still love it. It's fun, it's got good characters, it's got great action. It's got a coherent, interesting story with all sides of the conflict being sympathetic and flawed.

But it's the people that lift up Fighter G and 00 while hating SEED that completely mystify me.
