Yes, drama Is certainly a good medium for conveying a social message. Direct moralising is often resented and usually ignored. Drama is a presentation of a slice of life through characters placed In various situations. The attention of the spectator’s centres round their actions and reactions.
Most of them feel fully involved with the protagonists. The working out of the theme generally leaves a message – sometimes obvious and explicit but in most of the cases, indirect and implicit. The social message of these plays seems to come out of the interactions of the characters and their traits of character.
The victory of evil over good is usually portrayed indirectly. These days we find many plays centred around themes creating social awareness such as evils of drinking and smoking; dangers of pollution, child labour, the decreasing female ratio and need to empower women.
