Tidus' Opinion of Jecht

The first time we see Jecht really, it's from Tidus' POV. In a dream. Jecht mocks him openly.

However, we get a few real flashbacks:
YouTube - Final Fantasy X Cutscene 28 - The Jecht Shot Mark III

Also the scene on the Farplane:

Tidus: I think i just figured something out.. Why i hate my old man. Whenever my old man was around, my mother wouldn't even look at me.
[...]
I hated my old man even more.. But really, my old man...
Jidus: mommy!
Mother: just a sec, dear.
Jecht: Ah, go to him. He'll cry if you don't.

We also know he was a drunk from Tidus' memories and the Shoopuf story Auron will tell you at the Moonflow.

So, in the end, was Jecht a (verbally) abusive father? Laughing at your six-year-old son can't be that bright. That and he was a drunk.

Or is it all just really Tidus' mother issues?

I don't think he had any issues with his mother. It's definitely dad in this case.

It's the fact he loved his mother so much that he was jealous of Jecht.

So it is both really.

I am more interested in how the dream of the fayth reproduces. Does it happen when the fayths have wet dreams? :chocobo:
