Which is actually a good thing, lol. Mech worship is a negative aspect in Gundam, IMO. The mechs are there for the story, not the other way around.
It's just you. They've developed most of the characters, even the side characters, very well. We know their past (as seen in the flashbacks, which are rather short because they are kids) and dreams. We know exactly what makes them tick, yet they are still relatively unpredictable, like Mika's kiss or Orga's respect for brotherhood.
Thinking about it, I really like this show precisely because it isn't like a Gundam show.
