I've never met anyone who didn't like O'Brien!
I know, I know.
I'm one of the very few that can't stand O'Brien. Nothing about his character was interesting to me and I don't really care for the actor very much.
I'm Irish. Therefore I like O'Brien.
No, I really do like him though. He seems like he is a genuinely smart and nice guy, and he's a good engineer. He doesn't have the quick speedy answers and irrepressible zest for engineering that I see B'Elanna have on VOY, but still he ranks up there for me among the best in my eyes.
His wife is pretty one-dimensional and she annoyed me a little bit in the very beginning. I don't know why exactly. Their baby daughter is just so adorable though...I could look at that kid's face all day.
