To be honest, I'm not very happy. The original story is complete as it is, so it's outrageous to add or modify the images and script. However, games are a different media so I think it's fine. The thing I hate most about the games are that even though they use the name (Gundam SEED Destiny), the contents are totally no good... There are many people who think that way, and there are many staff members who work really hard on making (these games), so I don't object. However, spare me from the people who come and go "Director, you're happy too aren't you?" — Mitsuo Fukuda
As you can tell from the YMMV page, there are plenty of people who disagree with the director's opinion.
Director Mitsuo Fukuda is sometimes known as "Flashback 'Em All" or "Clip Show 'Em All'', due to his constant use of flashbacks and recap episodes, and in reference to Yoshiyuki Tomino's "Kill 'em All" nickname.
Mu La Flaga, The Zombie of Endymion, based on his original Red Baron moniker and the fact he came back from the dead with nothing more than a cool scar.
Captain Todeka is the Gundam Universe's Bruce Ironstaunch after he lets the Archangel go after they kidnap Cagalli and repeatedly taking Yuna to task for his grasp of tactics.
Flip Flop of God: Fukuda is frequently accused of these. How much is actually true and how much is the result of bad fan-translations of interviews he's given is up for debate.
The Strike Freedom's technical info seemingly gets RetConned every time a new model kit or MS design book is released, to the growing frustration of the fans. At this point there have been approximately five different explanations for its golden joints. To make matters worse, this doesn't apply to Infinite Justice; its joints are silver only to make them a matched set.
Franchise Killer: During the beginning of the series premiere, there were once hopes that the CE timeline could become the new UC. However, production troubles plagued the second half heavily divided the fanbase and a planned movie to wrap up the saga is in Development Hell, making creators and fans give up on the saga and move on to Mobile Suit Gundam 00.
Recycled Script: Destiny copied plot lines (with variations) from the last Gundam show, Gundam Seed, some examples being: Shinn and Stellar's encounter in a cave (in Destiny) being similar to Athrun and Cagalli's (in Seed), while the final battles in both shows are nearly identical, with the only difference being that in Destiny, the Three Ships Alliance's victory was a Curb-Stomp Battle (and in the TV version, a Flawless Victory).
Troubled Production: Very much describes the second half to the final thirds of the series, production-wise. Arguably the cause of a lot of the problems, especially the haphazard pacing, facing the series.
What Could Have Been: Shiho Hahnenfuss was to have been voiced by Nami Tamaki (who sang one of the theme songs in both SEED and SEED Destiny), but she declined the role.
