I both loved and hated the ending. From a philosophical perspective, it was excellent, but from a narrative perspective it was a bit underwhelming.

I wish it ended on episode 23. I may have liked the ending if it got more episodes to get used to, but the shift from the story to the philosophy lesson was too abrupt for my liking. It somewhat ruined my overall enjoyment of the show.

However, leading into the conclusion, I definitely felt my lack of knowledge impacted my enjoyment.

I think one needs to be a true Gundam fan to enjoy GQuuuuuuX. I watched first Gundam, but still felt confused at times. My biggest problem with the show, though, was the main trio and how underdeveloped those characters were. At least the animation and cinematography looked cool.
