actually as you said Nandi also says Mere Mahadev-but somehow Nandi always said it with love and devotion,not once it looked funny
however Raavan saying Mere Mahadev coupeled with moony eyes and heavy breathing was kind of funny-whoever directed the sequence somehow didnt get the devotion that Raavan has towards Mahadev projected as beautifully as Nandis devotion is projected-there was something wrong
and its not only me many others also found the portrayal strange-he was presented with the longing ala Sati and Parvati
...they are his consorts,Raavan is not Mahadevs consort-he is his Bhakt.and Bhakti wala pyaar isnt to be potrayed in the same way as Sati/Parvatis love.
i want the devotion presented like how it was presented in the ME when Raavan sees Mahadev-that is how it was supposed to be done
Yesterday the Raavan almost pining for Mahadev looked a little funny-it should be potrayed better-i didnt want to laugh but ended up laughing during those scenes
