I've been a zombie movie follower for some time (sometimes unwillingly). This movie obviously breaks ground as far as Bollywood goes - it is a respectable (?) zombie movie.
Any respectable camp zombie movie should have the following, IMHO - an unconvincing social message (e.g. Romero's "Dawn of the dead" was a backhanded critique of consumer capitalism and mall crawls, Danny Boyle's "28 days later" against irresponsible experimentation), references to other movies of the same genre (e.g. Shaun of the dead), and some innovative twist or variation.
Go Goa Gone scores on all three - it has a (tacked-on) message against drug culture, references to other zombie movies including Shaun of the dead (whose solutions are quickly discarded, since it should be obvious to the gentle viewer that desi/pardesi zombies in Goa are different from desi/British zombies in England), and an enjoyably terrible "solution". Also, good music, which Danny Boyle would concur with.
All in all, a respectable attempt!! As a camp horror addict, I am satisfied!! Also, a memorable quote that does not quite reach the heights of "When there is no more room in hell, the dead will walk the Earth" - it goes: "What do we know? What have we learned?"
