Bill Murray stars in a flat out comedy here, which is something he hasn't done in a long time (maybe since Rushmore?), while Melissa McCarthy plays down her usual persona (probably a good idea, seeing as Tammy just got slaughtered by critics). But, I don't know, I 'm not sold. How many times have we seen the curmudgeonly old guy brought out of his shell by a sweet kid? The most sentiment I can handle in this area goes back to About a Boy. This one looks pretty sappy. It's coming out October 24th.
