Tammy

...a road comedy—one that gets some good mileage out of the rapport between its unlikely travelmates.

...the movie hinges, of course, on Tammy. We aren't invited to admire her...

McCarthy has a way with a tossed-off ad lib—an aside or an observation or an insult—that provides some clever surprises when you think you’ve got this person all figured out.

The greatest aspect of her performance in Tammy is the range of dynamics, the subtle switches between crabby petulance and legitimate trauma which help the film to pack a considerable emotional wallop.
