Re: What "un-PC" stuff are you referring to in "Ace Ventura"?
It's 100% the Sean Young character. just handled in a completely hamfisted fashion... though I think it's partly meant to ape The Crying Game. but anyway, it comes off as more nasty (and unfunny) than anything else... forgive my bleeding liberal heart.
I watched Ace a while ago and it was mostly stupid. I cracked up at Jim Carrey "rewinding himself" but mostly got tired of his outbursts partway through.
