ANSWER: Yes, she is an overrated actress
Tamanna Bhatia is an Indian actress (Born 21 December 1989) is an Indian actress who predominantly works in South Indian films apart from appearing in Hindi films. Belonging to a Punjabi family with Sindhi descendant she was not able to debut in Punjabi movies but instead with her glamour and lesser skilled acting she got a top slot amongst the actresses in Tollywood or mainly South Indian Film Industry. This altogether proofs she is an overrated actress as she never won any critics choice award let it be National or Filmfare so how we see her is only as a diva and not an actress.
Her Bollywood debut was Himmatwala in which she was paired with Ajay Devgan and the film was directed Sajid Khan but what happened to this remake was a total disaster at the box office. If one goes by the looks she might be the best but by acting skills, she is the worst!
