Well this is more of a thread for complaints. Well let me throw in my five cents here.
My first complaint is the amount of reused scenes. I am so sick of see so and so getting killed by so and so with the same freakin attack again and again and again. I know you guys have to be sick of it too. I mean every battle I see a reused scene at some point and it just pisses me off. Same with the openings. Op3 and 4 have near identical scenes . Just pure annoying. The plethora of reused scenes is gonna drive me insane.
Second Complaint. Music. Near same music. Couldn't they have changed the music completely or something? And Wings of Words/Op4. What the hell is that. Same for I want to go to a place.../Ed3. That song also. They completely destroy the look and feel of GSD. With a lame opening and ending coupled with an episode recap leaves only about 17 to 18 minutes of the actual episode. They could've used that time wasted to explain and go more in depth to the many unanswered questions that have been stated in this thread already.
The entire if you don't accually see the person in the cockpit of a mobile suit combust then they are alive thing is getting really old. By all rights almost all the the current pilots should be dead right now. I mean really. By some strange turn of events Mwu survived, but I'm not gonna get into that and other people who should've died.
I have a lot more to post but I'll do it later.
EDIT: Them making Kira out to be a newtype now is just plain stupid in my opnion. He is already the ultimate coordinator. Soon he'll be the ultimate newtype to boot. They really are trying to turn Kira into a god of mobile suits. After seeing Shinn's work in the Destiny I thought "Hey maybe Shinn will be able to match Kira." but now all hope of that is gone. Athrun and Canard are the only ones left who even come close but I doubt that they could even handle him.
Pilot stupidity is also a major problem. When Shinn fought those Destroy's I kept questioning the the brains of the Destroy's pilots. If those destroys stayed in mobile armor mode they could've kept their shields projected and fired upon Destiny. The blatent disregard for battle strategies just pisses me off. But you know. Gundams are so powerful that they make battle strategies useless. I mean come on. Shinn's new light shield on destiny was able to repel a head on shot from Destroy's positron cannon. To me that is garbage.
