It's a Christmas movie. It won't get annoying if you put it on in the background but it will if you sit down and try to play ultra close attention to it. It's acceptable. Entire movie is held up by Danny DeVito's acting.
Edit January 16th, 2025: Thinking back on this it really wasn't good at all. It has an incest joke and a cross-dressing joke and overall wasn't that entertaining, and I found myself wishing for the movie to end before it finished. As Christian Di Leo said on Letterboxd:
What do you think Matthew Broderick feels worse about? Killing that mother and daughter in his 1987 drunk driving accident? Or starring in Deck The Halls?
