Drama is one of television's most important and challenging genres. The best dramatic series can encompass a wide variety of topics, from politics to supernatural crime, but what sets them apart is the quality of their writing. Without strong dialogue, plots and characters, high-budget shows with incredible casts can quickly wither on the vine. It's incredibly challenging to tell a meaningful story in under an hour but it's every drama's chief goal.
