There are many movies were I feel emotional with, some I sub-consiously link with my childhood past (The Land Before Time being one of them) and cry whilst with other movies that I feel emotional over I don't sub-conciously cry over as they don't have a profound effect on me as much.
There are only three movies that I do get emotional with on a regular basis (The Land Before Time, Bambi and The Lion King). All three, a parent (mainly the mother) dies during the film. These three films were a basis of a difficult time for me and although I didn't loose my mother I very nearly did. So; I do tend to link the 'experience' of what happened with these movies.
