An emo movie - up in the air

Watched the movie -up in the air
It reminds me of many things happening in life.
When I told dad about the movie, he said : aiyoh watching these movie only exposing yourself to more worries.
Thats what I always been hiding from, I only watch comedies or animations so that I would laugh off my head.
Guess one day, when you're old like the middle-aged man in the movie, you'll come to this question.
Do you want to be surrounded by people you do not know, have all the freedom, not having any responsibility on your shoulder?
Or you want to be surrounded by people whom you know, your friends & family, but not having so much of own travelling?
This movie reminds me of many unsolved question that have ran across my mind.
The mid-aged guy selected the first choice, but one day he realised he needs a companion. He went to the woman that he thought she's the same type of person. And realised she has a family.
But he's not alone, as he found his family, always there for him.

Its an emo movie, but meaningful to me.
It made me think.
But I still don't get why is this movie in the comedy genre. urgh.
