I only ever use those sites if i really disliked a movie but can't figure out why.
As a way to select a movie they're really pointless, I think a system that matches tastes of people and recommends movies based on that would be more promising.
I was surprised the Little Mermaid live action remake was so well received. Those live action remakes only even exist as a way to milk the older cows without paying royalties due to obscure Hollywood laws. I like Halle Barry's acting too, but a 94% audience rating? The fuck?!
