One way to do this would be to compare imdb's top 50 movies as voted on by females versus imdb's top 50 movies as voted on by males. You may complain about differences in sample size, since there are about 10 times more votes by males than females on imdb (why is that?). But with 10,000+ votes on most of these movies by females, I would still prefer these scores to any other measure.
Movies much higher on the female list: The Lord of the Rings (#4, 6, and 12 as opposed to #14, 20, and 31 on the overall list), Gone with the Wind (#11 vs #167 on overall list), Amelie (#14 vs. not on the male list), The Pianist (#17 vs. #56 on overall list), Pan's Labyrinth (#22 vs. #61 on overall list), Finding Nemo (#24 vs. 152 on overall list), The Notebook (#24 vs. not on the overall list), Beauty and the Beast (#34 vs. not on the overall list).
Movies much higher on the male list: The Good, The Bad, and The Ugly (#4 on male list, not on female list), Seven Samurai (#11 on male, not on female list), The Matrix (#25 on male list, not on female list), Se7en (#27 on male list, not on female list), Apocalypse Now (#31 on male list, not on female list), City of God (#18 on male list, not on female list).
I am truly amazed that the Matrix is not on the female list, since it probably has a high weight given that it is such a highly watched movie. Plus... Keanu Reeves! Females only give it a 8.3, and a 7.6 by females under 18, which is weird to me. But then again I'm not female.
If you are looking for biases in the top 250, this would be a good place to start, since there are so many more males voting on imdb than females. There is a clear trend on the male list toward movies with more violence, and a clear trend on the female list toward movies with more mushy stuff.
