Wiig really shines in the film, proving that her finely honed comic timing can make a character work even when the film ultimately doesn't.

Whatever their other gifts, they cannot find the fizz here and can never get Wiig to commit to the sort of film that she, even when she was making it, must have realized was beneath her in her post-”Bridesmaids” glory.

The blame belongs most plainly with Michelle Morgan’s script, which requires this gifted comedian to play straight woman to a supporting carnival of Indiewood types.

The keenest irony is that Imogene’s fake suicide note is the most convincing thing she’s ever written — which makes perverse sense since Girl Most Likely is DOA.

Tiny and well-intentioned but dramatically inert and sham-kooky, Girl Most Likely is for Kristen Wiig completists only, and even they may squirm at spending a whole movie waiting for her character to pull her head out of her ass.
