I just finished watching Gundam SEED and to my surprise it has become one of my favorites.... a surprise because I'm not a mecha fan... so as a result I have a couple of questions:

1. Are all the Gundam series as good as SEED? Is SEED the best of them? Are they as intense as SEED?

2. Are all the Gundam series related in some way? Not necessarily plotwise, but artist, character, production company, writer wise... any of those... If you could be especific about what series you are talking about I would appreciate it...

Thanks for any help provided
