I'll second (or third) "Flowers for Algernon" for genre stuff - I can't remember if I actually got teary-eyed but I certainly
felt teary-eyed.
Oddly, I was also strongly affected by the beautifully titled
The Cosmic Rape by Ted Sturgeon - also published in shorter form and sometimes in book form as the only slightly better "To Marry Medusa". Looks and sounds like a real tear-jerker, huh? Some sort of "cosmic yearning" passage or something.
I think that's about it. There've been a couple of movies that affected me - as I think I've mentioned before, a scene in
2010, of all things, has a kind of joyous, rather than sad, misty-eyed effect on me. But it's rare enough that I likely recall 'em all, though it's been a long time since anything's affected me like that.
No "gosh wow!"
or "boo hoo"? At all? Ever? You were a more stoic child than I, Gunga Din.
