Naga Munchetty, 47, has risked angering Grease fans after she confessed that she was not a fan of Olivia Newton-John's character, Sandy. Her admission came after her BBC Radio 5 Live show paid tribute to Olivia following her devastating death on Monday, aged 73.Naga welcomed Olivia Moore onto the show who is currently playing Sandy in Grease The Musical on London’s West End.The pair chatted with film critic Emily Murray about the late actress’ legacy and her performance in the 1978 classic movie.Then, Naga controversially admitted: “You know, the character of Sandy, I will be completely honest...she annoyed the hell out of me.”The stunned film critic gasped and questioned: “Really?!”Naga went on: “Yes! I thought she was a wet blanket to be completely honest.She was a wet fish, a jellyfish almost, spineless.“In the end she turned it around but the character changed her personality to suit a guy, which bugs the hell out of me.
