Nasha means intoxication or getting high. Unfortunately, nothing as such happens here. Its a kind of movie that built a lot of hype thru its trailers and promos. But in the end, its like flat beer.
The problem with Nasha is that it depends a lot on Poonam Pandey to deliver. However, the lady can't act. May be someone like Bipasha would have done wonders with this role. Remember Bipasha and the same director had made 'Jism' which was very good.
Also, we have seen so much of Pandey on the net that here in the movie she is over dressed...!! So all the burden of the movie falls on the young shoulders of Shivam Patil and boy he delivers. Shivam if groomed well, will turn out into a good actor. He beautifully portrays all the emotions like lover, jealously, anger, suspicion. He is the only reason I can suggest you to look at Nasha.
Even the love scenes are mediocre and this is surprising since Jism had some really hot scenes.
The supporting cast consisting of a bunch of young unknown actors are good and hats off to the director for choosing a beautiful location like Panchgani to shoot the movie.
