Let's!
TV -
Queer as Folk (UK and US),
Transparent,
Six Feet Under (not exclusively lgbt themed, but one of the main characters is gay and he and his boyfriend are still probably the most fully realized gay characters in all of TV),
Looking (one of the only current gay shows on TV, so why not),
DTLA (for a soapy guilty pleasure mess),
Angels in America,
Orange is the New Black (also not exclusively lgbt themed but a lot of the characters are lesbian, bi, and trans),
Noah's Arc (I haven't seen this but it's apparently decent),
Queer Eye for the Straight Guy (of course!!
)
