Terms of Endearment - I can still manage to watch this after having had cancer because I love the movie. It hits very close to home however. I never make it through the scene where she has to tell her kids she is going to die since I had cancer.
It scared the beejeebers out of me the first time I watched it, but it's a thriller, not horror. And I was hooked. I love, love, love this movie! Kevin Costner is great in this thriller. The ending is awesome.
