I always have mixed reactions to
It's a Wonderful Life. On one hand it is a celebration of the worth of friends and family and ends with a life is good and a good person will be rewarded in the end message. On the other hand in the end evil banker Mr. Potter gets to keep the money that he has stolen. Realistic I guess.
How the Grinch Stole Christmas on the other hand . . . It has The Grinch. It has Whoville. It has narration by Boris Karloff. A real classic.
