About the movie: "Bent It Like Beckham"

This is a movie that I never saw until 2 weeks ago. Personally, I liked, It was interesting, fun, etc. But something that really called my attention was the fact that the Indian culture was very emphasized in the movie. During the whole movie the mother of the protagonist (Jesminder) always was talking about the culture and the honor of the family. The movie also showed a bit about the Indian weddings and how this are a really big deal in the Indian culture. At first, someone would think that all the things about culture and honor in the movie would be a little exaggerated, but then, in the end of the movie I noticed that the director (Gurinder Chadha)  was in fact  a guy with Indian origins. So, considering this fact, and the fact that the movies usually do not show the things like they really are. I would like to ask, the Indian culture is really like this? It is exactly like in the movie? This is something that we really must considerer.
