I just posted this somewhere else:
"I was lurking this thread - because I like to lurk - and I don't really like being a hater or ruining a sanctuary for a particular fan base. I'm more of a "to each his own" type of person, but I saw this post and felt like I needed to speak up a bit. Possibly discuss the male human NPCs a bit with some people who actually enjoy them.
HERE WE GO ESSAY TIME:
Contrary to popular belief, the fact that people dislike Kaidan or Jacob but like male companions Garrus has little to do with the fact that he is alien, and therefore "more interesting". The cultural aspect can add depth to a character, but that isn't was truly shapes them. I LOVED Ashley (who is human) even though I disagree with her moral standpoints. She was very fleshed out and I admired her spirit. I loved the little stories about her sisters, her father, poems, why she was so deeply set in her ways etc. I also went with Alistair instead of Zev. in DA1. ****, I also love Zaeed.

Old man crush? Hell yes.
Ideally, I would like someone who could make me laugh or genuinely care about their family life. Kaidan is a very serious and considerate individual, but seems to have problems taking things lightly. He's a serious guy with a pretty serious past. Jacob is also pretty fleshed out in that he practically had to raise himself. He is so independent that he has trouble opening up to Shep. I admire that as well, but it isn't something many people can relate to. Its why many people assume he's cardboard because he doesn't coddle or open up to the player all the time. Kind of like Sten in DA (who I loved) I understand why people love them. However, he doesn't really have much wit/dry humor to compliment his serious independent nature. Both human males are quiet, independent, serious, and strong. Garrus and Wrex almost ALWAYS make me laugh, even though they have serious problems.
I'm actually actively excited about James Vega and have a playthrough set aside that has a completely clean romance slate, just incase a new romance option was available. I hope that he's more positive."
