AIR had fucking nonsense that was NOT built up well. It was literally melodrama -- type-cast characters who are sad because of archetypal (i.e. cliche) sad things that happen to them.
The second part was NOT well linked into the first or third parts, and the third part was just plain random bullshit.
If you think AIR was good because a GIRL ACTED CUTE and then THAT GIRL DIED, you have abysmally low standards. AIR was shit. Allegedly the game was better (as in: had a coherent plot).
Seriously, if you liked AIR, you'd likely enjoy a random montage of crying girls walking slowly with sad music playing in the background.
AIR was shit.
This is fact.
It's true all day and all night.
