What's more likely to get you to date a guy/girl? Their looks or their personality?
Personally, I'm pretty shallow, so if I meet someone in real life then to begin with unless they're physically attractive, I won't be interested.
Having said that however, I find that especially when watching TV there'll be a character whose personality is so fantastic that I can't help wishing they were real. Okay, so even if he was the most charismatic person around, I still wouldn't sleep with the elephant man (gotta draw a line somewhere) but on the whole, their looks come second to their personality.
