Clannad After Story ending?! Your thoughts *Spoiler*?

Okay I just got done with Clannad After Story and I gotta say it made me cry(And I'm a guy :D) Anyways the ending to me was unexpecting. I mean I just watched all of the crying and painfulness and then they decided to make a happy ending which was weird but satisfying. My favorite part was the story with the cat and the woman that owned a dorm. I thought it was a cute yet sad story. Anyways Nagisa's daughter looked so identical. xD So overall I loved it. And I thought the dream world parts were a methaphor. So what was your thoughts on After Story?
