Bollywood films are mostly musicals, and are expected to contain catchy music in the form of song-and-dance numbers woven into the script. A film's success often depends on the quality of such musical numbers. Indeed, a film's music is often released before the movie itself and helps increase the audience.

Indian audiences expect full value for their money, with a good entertainer generally referred to as "paisa" "vasool", (literally, "money's worth"). Songs and dances, love triangles, comedy and dare-devil thrills are all mixed up in a three-hour-long extravaganza with an intermission. Such movies are called "masala" films, after the Hindi word for a spice mixture. Like "masalas", these movies are a mixture of many things such as action, comedy, romance etc. Most films have "heroes" who are able to fight off villains all by themselves.

Bollywood plots have tended to be melodramatic. They frequently employ formulaic ingredients such as star-crossed lovers and angry parents, love triangles, family ties, sacrifice, corrupt politicians, kidnappers, conniving villains, courtesans with hearts of gold, long-lost relatives and siblings separated by fate, dramatic reversals of fortune, and convenient coincidences.

There have always been Indian films with more artistic aims and more sophisticated stories, both inside and outside the Bollywood tradition (see Parallel Cinema). They often lost out at the box office to movies with more mass appeal. Bollywood conventions are changing, however. A large Indian diaspora in English speaking countries, and increased Western influence at home, have nudged Bollywood films closer to Hollywood models.

Film critic Lata Khubchandani writes,"..our earliest films...had liberal doses of sex and kissing scenes in them. Strangely, it was after Independence the censor board came into being and so did all the strictures." Plots now tend to feature Westernised urbanites dating and dancing in clubs rather than centering on pre-arranged marriages. Though these changes can widely be seen in contemporary Bollywood, traditional conservative ways of Indian culture continue to exist in India outside the industry and an element of resistance by some to western-based influences. Despite this, Bollywood continues to play a major role in fashion in India. Indeed some studies into fashion in India have revealed that some people are unaware that the changing nature of fashion in Bollywood films which are presented to them are often influenced by globalisation and many consider the clothes worn by Bollywood actors as authentically Indian.
