I have seen Okadu, so I know the difference. Okadu is a boring movie IMO, no comedy (dad says son (MB) to go practice Kabadi, no thirutu thanamaana playing the game). Screenplay is very slow, one thing that should be appreciated is, they had built a duplicate 'Charminar' (for Light house in tamil), the director does like this as he did built the set of 'Madurai Meenakshi amman temple' in a movie if I am not wrong.
