I watched this again last night with a positively open mind. Much better. I appreciate it as it is and can fully understand why it has become so popular. My personal film database entry goes like this:
It's a Wonderful Life **
(1946/Capra/US)
A man rises, falls, and tries to commit suicide, but an angel saves him.
Popular fantasy rehash of A Christmas Carol which isn't quite the classic to which it aspires; there are many delights to be found, though cutting would have helped.
