"Girls" has Really Gone Downhill

I remember watching the first series of the HBO Original Series Girls and being absolutely amazed.  The first season did a great job chronicling the life and difficulties of an American college graduate in today's working world, and nearly everyone I knew really enjoyed the first season.  I recently started watching the second season, and it's like I'm watching a different show.  All of the witty greatness and real life application had been replaced by countless uncomfortable moments and episodes that left me wondering why I wasted 25 minutes of my life watching such a terrible show.  Lena Dunham received a ton of credit and notoriety after the success of the first season of Girls, and I wonder if it went to head and distracted her from putting out another good product.  That or she was a one hit wonder, but in any case the second season of Girls is horrendous.  I think it's in it's third season now, but honestly I don't care enough to investigate.  It's just disappointing to see a show with such potential nose dive.
