People love Bollywood dances because there are no defined rules like classical dance styles. Some people love Bollywood because it exposes them to Indian culture. Others enjoy the vibrant music and colorful outfits. Style of dancing in earlier Bollywood films was based on Indian classical dance or folk dances from various parts of India. In the late 50s & 60s, group dances began to evolve in Bollywood as films and choreographers started managing larger groups of dancers with influences from folk dances.
