Super Fun Night Wednesdays, 9:30 p.m., ABC.

In small parts in movies like Bridesmaids and Pitch Perfect, Australian comedian Rebel Wilson has proven herself an effective scene-stealer, but her new sitcom Super Fun Night demonstrates that she might be better in small doses. Wilson (who also created the show) plays Kimmie, one of three awkward best friends who spend every Friday night together and shun other social interactions. But when Kimmie gets a promotion at work, she decides to expand her social life and bring her friends with her. Super Fun Night could be Wilson’s version of The Mindy Project (which is uneven but exuberant), but instead it’s a mix of obnoxious, unlikeable characters and mean-spirited jokes. Wilson’s choices, from affecting an unconvincing American accent to constantly putting Kimmie in humiliating situations, are more irritating than endearing. Kimmie, like Wilson herself, should be someone to root for, not someone to avoid. That’s fine for a flashy supporting character, but it doesn’t work for the star of the show.
