1) Comedy as a genre is complex, with many different forms including black comedy, slapstick, satire, and parody. Comedies often rely less on standard narrative devices than other genres.
2) There is no single definition of comedy - it aims to provoke laughter but can also be used briefly in other genres. A comedy typically depicts everyday life and ends happily, though laughter is not its sole purpose.
3) Many successful comedies are genre hybrids, blending elements of romance, drama, and other styles through their narratives while still prioritizing humor. Straight comedies rely more on sophisticated use of comic conventions alone to appeal to broad audiences.
