This may shock you, but we've had this thread already. http://forums.digitalpoint.com/showthread.php?t=1233814 I like anything with gay robots and space princesses in it.
People liked Om Shanti Om and Ghajini??? Both are horrible movies. I don;t have any particular fav romantic movie...maybe Sholay? Last year, I liked Jodha Akbar and U, Me Aur Hum. In English, i don't really like watching romantic movies.
