Tina was a good example of how the FotW concept really rocked for this show. When they casted well, they were this good mix of scary and human. Tina was this great example of how the show had this original X-Files/Twin Peaks vibe. Things were not what they seemed on the surface.
It got old when they did FOTW over and over, but yeah the hidden passions/outer wholesome image thing was cool. Tina really personified this as she literally wore the wrong face.
Roger Nixon was really a great villain. He' s introduced in this one and MR's arrogant smile as Lex tells Roger he's going to erase his existance and give him a new identity to make his life miserable was glorious.
I love his smugness when he thinks he's got Lex over a barrel, and his dawning horror as he realizes he's in way over his head.
The jockying was good. Again, scandal (image) vs. secrets and lies serving the greater good. Nice tension.
He wasn't being a complainer, he was just expressing his sincere frustration at not understanding himself more which I'm sure is something adopted kids everywhere could relate to.
But once he learns how to use it and realizes he can do good with it (he can find the bank robber, clear Lex's name, return the stolen money) that angst disappears. It's no longer a detriment, it's an asset.
It's the tension, the back and forth that's good. I have no issue with Clark having angst, but the moments of joy and satisfaction seems to be gone these days.
