Legality of displaying movie review scores

I am building a site that is in part about movies and would like to display the review scores from a few sites like IMDB and metacritic and was wondering if this might fall under fair use or if I would be pushing my luck?

I think you would be pushing your luck. Even if you fashioned a fair use arguement, if they sue you anyway you would be looking at $50K to $100K in legal fees. I do not think the fight would not be worth the value of the use.
