My favourite movie description was in the U.K.'s version of TV Guide.
BG for the US - Over there, at least a decade ago, Christmas day was when all the TV stations try to show the newest & best movies - often this was the first time they aired on TV after being shown at the cinema. So in this context, a "Christmas movie" is just a regular movie airing, probably on TV the first time, at Christmas.
So, all the other reviews were long and detailed, but this one review simply said
"Turn on the oven, it's another Christmas turkey".
I can't even recall the movie, but I just loved that review - brief and to the point
