I certainly don't think the same way. One of the reasons I love KOTOR is that it doesn't have the extensive "rich dialogue" like other bioware games have. Not everything is spelled out for you like it is in other bioware games- or K2. I am more free to fill in the details and backstory myself, going by nonverbal clues of which are many in the game.
After I played Dragon Age Origins I appreciated KOTOR 1 even more, because I get tired of "rich dialogue." Rich dialogue is ultimately too limiting for me. It even feels manipulative of Companion characters- which ironically suits the Exile in K2 who is essentially manipulating Companion characters into becoming Jedi, or to give bonus powers.
However, I can never fully immerse myself into roleplaying my Exile as I can my Revan, light side or dark side. There's too much defined for the Exile in many of the dialogue options, which doesn't really reflect my own reactions. KOTOR 1's looser style lets me be more immersed.
I know a lot of people prefer a rich dialogue, or having their character more defined for them, but that's a matter of preference, not that a game is shallow because it doesn't have a lot of rich dialogue.
If you want to make and release a mod that provides more definition and rich dialogue for the player character, that's great, because I do believe in options and it might encourage more people to play and perhaps mod for KOTOR 1, so I would support it for those aspects. But it doesn't mean the game, or the existing dialogue, however imperfect in other ways, is shallow.
