White Christmas: I don't know if this movie is really all that amazing, however it is a holiday classic and tradition. It's funny how so many "Christmas" movies really have little to do with the holiday. White Christmas is still an enjoyable movie with great song and dance numbers. I wish it would snow again even though we had a white Christmas.
The Italian Job: First off I wish to clarify that this in not the more recent version with Mark Walberg, etc. this is the original movie with Michael Caine. I imagine you weren't aware that there was an original version, nor was I, I got this version by mistake from the library. This movie really is rather dreadful. The ending was appalling, the plot was weak, I would recommend just passing on this movie all together unless you want to see it for the beautiful scenery in the Alps.
