Gundam was a show that while heavily defined by action sequences, but also displayed various aspects of human emotions.
How scary war is, about how enemy might be an enemy but they can't be considered evil, clash of values between characters, etc. Gundam series portrayed those clearly, so Gundam was always a great show that both risen your adrenaline by awesome actions while at the same time moved your heart.
This latest movie of 00 have no such things...
First, they fight freaking aliens, which was a taboo for Gundam series. The reason is clear, fighting a mindless being like robot or monster was always less heart moving than fighting a sentient being and especially of the same race like humans. You can massacre millions of robots and monsters and you won't feel a thing. Maybe for other show is okay, but not Gundam, because it wants to tell you that every fight has a meaning. While watching they fire their beams, rounds, and missiles everywhere and aliens exploding here and there, what I thought was.... this is as fun as me spraying my room with insecticides to kill mosquitoes... which is not fun at all and more like a chore.
Emotionally driven combat is long gone in this one. Simply said, this is so not Gundam.
I still hate the characters from the series as well, especially "discount Hiro Yui" ups I mean Setsuna The Gundam Lover, Insignificant princess, etc. But I still like the series though, but not this movie, this movie is a stain to the franchise.
