Gundam SEED isn't terrible. It's actually quite good and I do recommend people to watch it. Like any show, there are a couple of flaws and annoying things about it, but I'd rather not pick at them.
I do agree with some of the complaints that the battles drag out for too long. But hey, they have 50 episodes to fill. So it's a bit of a downfall if you're not into the whole Gundam fighting scenes. The thing that I enjoy most about this show is the characters and plot. The ending is phenomenal. The series is packed with twists and turns. Character development doesn't just focus on the few main characters, but also the supporting characters as well. The music is also an A+. And I'm not just talking about the catchy J-Pop openings and endings, but the score itself is so well done.
Kira Yamato is your stereotypical, invincible television hero. That's to be expected, isn't it? He's very kind and likable. I'm really REALLY glad he's not one of those angry, violent characters who spends half the show swearing and being moody for no apparent reason. Le Creuset, the antagonist, is rather one-dimensional. His whole history and motives are crammed into one episode near the end, and you're like, "OHH now I get it... too bad the series is going to end soon."
(And props to the team for perfecting Flay as "the character everyone hates".)
The English dub is very well done. There are a few awkward dubbing moments, but it's better than a lot of other anime. If you don't want to read subtitles, watch the dub. You're not going to miss a lot.
In a few final words, Gundam SEED is not flawless, nor the "best Gundam show ever", but it is definitely watchable and enjoyable.
