Well I'm in the minority with this...
I actually, admittedly narrowly, enjoyed 'The Santa Clause 3: The Escape Clause' - terrible title, mind. Most other reviewers clearly didn't and I respect that, but I genuinely found it alright. It's definitely the weakest entry of the series, yet I still found it entertaining enough.
Martin Short (Jack Frost) is the star of this second sequel to 1994's 'The Santa Clause', outshining lead Tim Allen; who is still decent, by the way. I love Short's character design, he looks ridiculous in the nicest possible way and Frost (why him, I'm not sure I admit) makes for a relatively good villain. All the other cast members take a backseat, while the storyline of Alan Arkin's Bud is very forgettable and arguably needless.
I was expecting to dislike this and the preceding follow-up, but to my surprise they are actually - at least to me - harmlessly fun festive films.
