Actually it's a movie called "Grim Prairie Tales". I only was able to look it up because I remember that Brad Douriff was in this. But it did remind me of that situation in American Gods too...need to check how it stands with that TV adaptation...
In FFTA, your goal is to leave Ivalice and go home. Unfortunately, this means your friend's mom will go back to being dead and your little brother will return to being a sickly cripple in a wheel chair. Also you have to possibly destroy Ivalice and all life in it to go home.
The jokes are that Marche, the protagonist, is a huge jerkass whose selfish desire to go home comes at the cost of everyone around him.
People always forget that the flipside of this is that Marche's friends are delusional and choosing to trap him in a false world where he will never see his parents again, and while his brother might have the noble cause of doing it to be able to walk, his friend's desire to be with his mother is no more just than his wish to go home is evil, and the girl wants to trap him in this hellscape because, well, she doesn't like the color of her hair. So basically, everyone in FFTA is a gigantic dick and you have the good luck to play as the victorious dick.
It's nice that there's at least some perceived duality. It gives the game at least one redeeming factor for stealing the name of the best RPG story ever.
I've heard quite some people say 'yeah, I played FFT, wasn't that great' because of this mediocre spin-off of the spin-off.
