I have watched many Bollywood films and I have to say that in some of them especially those depicting NRIs there is shown a very biased picture of foreign countries and cultures.
I can indicate a "Swades" film as the only one where a director was really open-minded and showed everything with high prudence.
In "Pardes" we see unfortunately that NRIs lost completely their roots and went into some kind of "worse" and poor culture which is - of course - the culture of the U. S. as the main country of all comparisons. I remember in some other case in "Salaam Namaste" were shown NRIs living in Australia as an exception to the most of movies showing the NRIs in the USA.
I many Bollywood movies I have seen that narrow-minded approach showing a bipolar view & comparison like India - the best country in the world and the REST which is like a savage and dark land.
That way of depicting isn't wise just puts a film in the 2nd category movies with many things to be improved by some way better writer and director. If sb wanna make a film about social issues should firstly consider all diligently to not create another "one of many" average movie.
