SRK's popularity and the dramatisation to the film will win hands on with the public! Even the rural areas would watch OSO over Saawariyan just for its popular subject. Saawriyan will be a superior product in all aspects and will stand on its own but will find it difficult to bit OSO unless OSO is as bad as Paheli...OSO does not demand an itellectual understanding of the film like Paheli..hence my bet is OSO will be a winner. My personal prefeence - Saawariyan
