The kid...........spoiler

Did they make Paris, Texas 2 where they showed that the kid's life was fucked up because he reunited with his mother?

No. We have no idea what happened. You're a pessimist who assumes the mother would be incapable of giving the kid a good life.

It's not science fiction for a person to be a total fuck-up and then grow into an upstanding and responsible adult because they have a child. It happens in "real life" every day.

Jane clearly stumbled after she had Hunter. She was so young. Travis' issues didn't help. The story is about them finding redemption and hope. I suppose those things naturally won't resonate with a viewer who harbors a pessimistic outlook.

Yes, he would be better off with Walt and Anne. But maybe he'll be okay with his mother, even though she's a stripper or prostitute or whatever the hell she is. She's young and smart and good looking, so she'll probably get her shit together and marry some rich guy.
