What is the main conflict in The Critic by Richard Brinsley Sheridan?

The Critic first premiered at London's Drury Lane Theatre on October 30, 1779. As its title suggests, the play follows a day in the life of a critic, Mr. Dangle, as he is entreated by members of the theatrical world for his patronage and support; the play's second and third acts feature Dangle (and another critic, Mr. Sneer) watching the rehearsal of The Spanish Armada, an historical tragedy written by their acquaintance, Mr. Puff. Although Puff's play is meant to arouse pity and fear—the two required tragic emotions according to classical standards—his play is a laughable hodgepodge of bombastic language and ludicrous events.
