I just feel that Gundam is being targeted to a younger demographic, which is fine and I understand why, just has lost my taste a little bit. I grew up watching Gundam Wing like most on Toonami, and it still rocks as my favorite series....well 00 is up next to it but still, those are standards I live up to. G Gundam I enjoyed as well, just not as much as Wing. Seed was really enjoyable for me to watched and I liked it a lot, never saw Seed Destiny, and 00 like stated before I enjoyed.
So I do believe it is more of a kids show now, just based on my enjoyments of the older series. It is a new generation so it is being aimed at to a younger demographic with younger pilots and main characters with younger companions. Age did nothing for me, and with the new series Build Fighters, I see the same thing.
Just cause it is a kids show, doesn't mean it can't be enjoyable for some older than the demographic being aimed at. Just for some fans, like myself, it doesn't fit our taste.
