FYI, if you have the IMDB ID for a movie, then you can link to Rotten Tomatoes using that IMDB ID.
Using the IMDB ID number, "0079501", you may access the Rotten Tomatoes Mad Max page using the following URL: Mad Max: http://www.rottentomatoes.com/alias?type=imdbid&s=007950...
I know you probably can't display the rotten tomatoes score, but it would be interesting to have that data internally.
I challenge anyone to find a movie with an RT score below 40% or IMDB score below 4/10 that was worth watching.
