Rob and Conall prevail once again, negotiating their way through the hellish landscape of the future to once again deliver to the world tale of a Christmas Classic (or at least, a spinoff of a Christmas Classic). Where once 'Home Alone' was ripped off with a dog, this time it's "The Karate Kid". Once again there is a tenuous Saved by the Bell connection. Once again, Dean Cain is of course present.   NON-SBTB CHRISTMAS (well not really) MOVIE: 'The Dog Who Saved Summer' (starring Mario Lopez as Zeus the Dog!)
