Blastphamy!! A Christmas Story is a great Christmas movie. I watch it every year. Though I agree that "It's a Wonderful Life" is also a great movie.
My favorite Christmas movies:
1) The Bishops Wife (1947, Cary Grant, David Niven, Loretta Young)
2) A Christmas Story (1983, written and narrated by Jean Shepherd)
3) A Christmas Carol (1938, Owen/ 1951, Sim/ 1984, Scott)
4) White Christmas (1954, Bing Crosby, Danny Kaye)
5) Miracle on 34th Street (1947, Maureen OHara, Edmund Gwenn)
6) Its a Wonderful Life (1946, Jimmy Stewart, Donna Reed)
