As big Tiny Furniture fans, we’ve been closely following the progress of Lena Dunham’s new Judd Apatow-backed HBO series, Girls, from development deal to teaser to premiere-date announcement. Now that the show’s April 15th debut is less than two months away, the first substantive trailer has surfaced, and it’s pretty great. We see Dunham’s 24-year-old character get cut off by her parents, engage in some awkward sex with a dude who treats her like crap, endure the slings and arrows of a dozen friends who want her to get over herself, fall on her face, and dispense such post-college-Angela-Chase-like observations as, “My entire life has been one ridiculous mistake after another.” All of which is to say that Girls is shaping up to be essential viewing. Check out the trailer after the jump, and let us know if you’re equally enthused.
