Grudge Match isn’t a good movie, but I understand its function. With relatives getting together for the holidays, there has to be something you can see together at a theater and not find completely mortifying. You’re not taking your grandparents to see The Wolf of Wall Street or American Hustle, because nobody needs to cringe that often. So it’s Saving Mr. Banks, or this movie, or the somewhat more puzzling Secret Life of Walter Mitty.
Grudge Match doesn’t offend, although it rarely comes to life, either.
