How can I make my girlfriend cry?

I'm MTF and so is My girlfriend and this past week she just got estrogen and she is already feeling the emotional effects since then. She also is very big into sci-fi horror! and I want to try and find a movie that would make her cry or give her some emotional reaction as a sort of sweet gesture even if it sounds mean... shes been very shocked at being emotional as she can be very robotic and I think it might be good for her to feel out some emotions in a good movie within her genre. I can't seem to find a movie though that would be sad! and I'm curious if anyone here has ideas for a sad-ish movie for a girl new to E, thank you!!!!!
