Depp is cool as fuck. He walked the planet as a god in his youth, had every woman wanting to bang him, and he treated it all with such indifference. He stuck with his weirdo niche films, never tried to be a celebrity, never did the plastic surgery route in an attempt to maintain his looks - he just smashed shitloads of drugs and partied with other weirdos. If he just fixed his teeth and lost weight, he'd still look great.
Plus, when that cunt Heard and her misandrist Hollywood cronies tried to ruin his life, he fought back with dignity and won. You gotta respect that.
