Anon here. I posted that thread. It evendually eneded up with one poster constantly complaining about how KBJ tries to be "funny". Odd, as I thought Trigun also had moments when it tries to be "funny".
I was about to post my response to the GL recomenndation when I got cut off. Basically, I want a compelling plot that justifies itself, and the last "mecha" anime I've seen was Bubblegum Crisis. Overall, light story, good action. Just anything to get me to pop the next episode.
