I find that women's taste in men seems to be pretty subjective. For instance, let's say I walk into a room full of 20 straight males and 20 straight females. If I name a female celebrity like Jessica Alba, I'll probably get 10 guys who think she's hot, 5 who think she's not that great, and another 5 who are on the fence.
But if I name a male celebrity like Brad Pitt, I'll get 5 girls who think he's hot, 5 who think he's ugly, 5 who don't care, and another 5 offering up opinions about who they think is hot.
