LFM: What genre were the plays?
Broadly speaking?
I would call the genre "Kurt Vonnegut and Judy Blume's melodramatic teenage bastard".
Lots of fifteen-year-old-who-thinks-he's-clever touches like... oh... self-aware narrators who realize that when the play ends it is their death, a high school janitor with the backstory of being a Westchester County blueblood and fated to spend his life falling sideways through alternate universes looking for a place where his best friend isn't dead, religion-as-myth analogies toward Gilgamesh/Tiresias/Catholic-relic-mysticism...
Yet grounded by plots of childishly-semi-autobiographical small towns full of old secrets, sensitive nerds who pine after girls whose engines are actually revved by jerks with leather jackets and bass guitars... and above all else... the appropos of nothing talkiness of a young writer over-enamoured with the early-to-mid Nineties slacker-romantic-comedies both of the indie-navel-gazing variety and the Brat-Pack-trying-to-find-adult-roles variety.
Your standard "intellectually-precocious but emotionally-stunted teenager" stuff except with the amp turned up to eleven.
