5. San Francisco, CA - September 8, 2015
Battling a cold and cough, Grande looked lost amid a too-busy stage production at the Shoreline Amphitheater. Fireworks and special effects couldn't make up for the pop diva's lack of charisma and her failure to interact with fans.

The 2015 Honeymoon Tour was Grande's first time headlining arenas, and it showed. Featuring cringeworthy video cameos by Big Sean and Mac Miller, her uninspired performance at the BMO Harris Bradley Center felt like a dress rehearsal.

Grande's voice is her strong suit, but it was buried beneath an over-produced show marred by bad lighting, bad costumes, and too many backup dancers. And who thought distorted vocal effects would be a good idea?
