I would definitely use a website like that.
I'm of an age in life where I won't watch a movie where I know in advance that:
1) An animal dies (unless it's to save the life of a nicer animal or a nice human).
2) A child dies under just about any circumstances (maybe if he or she is possessed by a demon and there's no other way to end his ruinous ways).
3) Where a good father loses custody of his child.
I may be the only kid who hated Charlotte's Web and Charlotte was a freakin’ spider. Life Is Beautiful was a fantastic movie that I wouldn't have watched if I knew how it ended even though it violates none of the above-mentioned principles.
Interestingly, I have nothing against hunting but I don't care for cinematic depictions of it and I wouldn't hunt myself except to feed me or my family.
No horror movies for date night? Wow. Horror movies for date night was one of my pro tips in my younger years! It was my experience that many girls get very clingy when scared.
