Suitably amusing.
With that said, 'Christmas with the Kranks' certainly starts brighter than it ends. I found fun in the opening portion, especially with the two leads. I didn't like the ending as much, I found it too sappy and untidy. The run time is short though, so that doesn't hamper things much.
Tim Allen and Jamie Lee Curtis are enjoyable at the forefront of the film, with Dan Aykroyd joining them in that bracket with his arrival. The rest of the cast are fine. The plot isn't anything majorly fresh, but it entertained me enough. Fun film.
