We already had some very really entertaining and so called sf movies like 'Krrish' and 'Koi Mil Gaya' having the elements of sci-fi.Even earlier we had Mr.India which unexploited the fantasy of invisibility to woo audience to cinema halls.It was a box office hit film .
But initial response from film goers is not encouraging .Though I have not seen movie myself but the comments which are incessantly pouring in discourage me to see the movie.
According to some it is a ridiculous and childish effort to ape the Hollywood's sci fi movies .
