The librarian in me is listing them by genre, and some titles will appear in more than one genre. And here's my caveat: I am not an expert in reviewing movies. I don't know all the technical stuff that goes on behind them. I usually go to a movie for entertainment, not torture, so the only heartrending or uncomfortable ones I list are movies I think are important to see*, usually involving some historical event or courageous person. The movies are in alphabetical order within each genre.

I didn't choose these for the actors or an outstanding performance or an original idea. I chose them for the stories they told, and for most of them, they made me feel good walking out of the theater. I wouldn't mind seeing some of them again and again. I don't mind admitting that I like happy endings. I want a movie to surprise me, thrill me, bring me to tears, and/or to make me laugh. The Pixar movies almost always hit every range of emotion in me-- they are all so well done. Avatar blew me away with the technology and creativity. I didn't go see it for all the subtle and blatant environmental messages. I went to watch a good story, and it didn't disappoint me.
I like a good romantic movie, but I don't like to watch graphic nudity or sex in a movie. It makes me feel like a peeping Tom, and I believe most stories can be told just fine without it, or leave it to our imaginations, please. One of the most romantic scenes that I've seen in a movie is in The Last of the Mohicans when Hawkeye and Cora are hugging each other. [And I realize the book is very different from the movie]. Every time I see Pride and Prejudice, I love it even more.
I'm sure there are other movies that I can add to this list, but these will keep my friend busy for a while.
