I thought I wouldn't buy it, but in the end, I did. As to the why, I'm not really sure. It's obvious from my reviews that I didn't think that SEED Destiny was a bad series, it just wasn't quite SEED. The art was more polished than SEED, but there were so many inconsistencies.

I watched a tiny bit because I was curious about the dubbing. I've been forcing friends to watch Gundam SEED from the beginning, and it has been a necessity to watch the dub for them because we're often playing a game at the same time or eating dinner or something along those lines. Most of the dub voices in SEED aren't bad - they just get emotional inflections wrong.

The exceptions:
1) Lacus Clyne - the English acting voice makes me want to rip my ears off to avoid hearing any more. It might not be so bad if they hadn't redubbed her singing as well - completely changing the words of her songs to make them sugar pop. Luckily, for the rest of the songs (so far) they didn't redub those, so I'm hoping I can survive to finish the dvds with my friends. It just... pains me.
2) Natarle's "Fire!" with a Texan accent... yeah.... something not right about that.
3) The narrator's horrible enthusiasm at the end of each episode - "Fly through the hoops of fire, GUNDAM!" It didn't sound as lame in Japanese to me, but I might have missed out on the Japanese inflection to imply lameness.

Most of the characters in the Destiny dub seem okay, with the exception of the guy driving the jeep with Lunamaria in episode 1 - I don't know what they were smoking, but he sounds like he's 7 years old and it just doesn't match. Arthur with a British accent oddly works. Shinn and Lunamaria sound okay - I'll have to hear more speaking by them to make a proper analysis of them.

I guess in the end I'm a sucker for all things SEED - hey, I did buy Never Ending Tomorrow! But we'll see if I finish buying Destiny.

(If you were a betting man, you should bet on "yes" for me being a sucker and buying those dvds)
