Eh, I've heard responses either way. I only really liked the original because of nostalgia value (got sick as **** of it because SEED was like the first anime I watched after rediscovering it, and it was the english dub that used the same 30 second clip of it FOR FIFTY GODDAMN EPISODES, so the twist on it was welcome.
It wasn't part of the initial plans to have a second opening theme, I just happened across it one day and went welp why not.
I will agree that objectively speaking in terms of musical composition the original is better, but I still really can't stand listen to it and it kind of makes me want to PUNCH SOMEONE IN THE FACE every time I hear it because WHO THE HELL thought that using the same clip for 50 episodes was a good idea?!? It's not like there weren't others available, but no, lazy as ****. thus I conclude that DUBS SUCK.
