I've never watched "It's a Wonderful Life"(is that bad?)
IAWL is great IF you've never suffered from major depression.
HOWEVER,
It's one of those movies that you find yourself going 'huh, yeah, but life COULD be better for the world if lots of folks weren't born'...
It's dark and sad to me. So I usually just stop watching about half way through it.
And Clarence gets on my nerves.
It must be seen. It's been my favorite since I was a young lad.
