"The stand out performance of the night came from Poppy Tierney as Harley Quinn who was fun, naive and deadly in equal measure.. Harley was definitely the star of the show.."

"Among the cast for villains, it is Poppy Tierney who steals the show, playing the Joker's side-kick, Harley quinn, as a demented, dumbed-down Cyndi Lauper."

"Then there’s Harley Quinn.. From the moment she’s introduced she steals the show, not only providing a measure of comic relief, but also one of the more sympathetic, better written characters in the piece as well. While that has a lot to do with the character, it’s clear that most of this is down to Poppy Tierney’s performance."

"..the cast were all admirable, especially Poppy Tierney as Harley Quinn, who stole the show from the Joker and was easily the best of the bad guys.."
