Not only because it's terrible, although it is, but rather because one desperately hoped that the beloved actor would go out on a high note. Unfortunately, that's not the case with this dysfunctional family holiday comedy that squanders the talents of its impressive cast who presumably signed on merely to work with the comedy legend.

Every so often, a movie comes along that begs the question, “With a cast this good, how bad could it be?” The answer is ”This bad.” Even with a powerhouse ensemble that includes Williams, Joel McHale, Candice Bergen, Oliver Platt, Lauren Graham, Wendi McClendon-Covey, Clark Duke, and Tim Heidecker, there are almost no “Friggin'” laughs to be found.
