At some point during this season of Glee — perhaps when a trans choir performed "I Know Where I've Been" from Hairspray, or the episode that managed to include not one but two same-sex weddings in the space of an hour — it became clear that the LGBT-heavy musical dramedy series had, while no one was paying attention, reached unprecedented levels of queerness. Yes, Glee has been gay from the get-go, but its final season is more focused on the spectrum of sexual and gender identity than ever before.

While critics and audiences largely abandoned Glee — which ends its run on March 20 — at some point between its celebrated pilot episode and its truncated final sixth season, those who have stuck around are witnessing something genuinely transgressive for major network primetime television. It'd be challenging to think of another network series that has celebrated the beauty of difference better. After all, Glee is not just gay: It's unabashedly queer.

And the show has never been queerer. Season 6 has seen the joint weddings of Kurt (Chris Colfer) and Blaine (Darren Criss), and Santana (Naya Rivera) and Brittany (Heather Morris), as well as Coach Beiste (Dot-Marie Jones) coming out as trans. The latter storyline in particular does a fair amount to make up for the series never fully exploring its last trans character, Unique (Alex Newell), who reappeared this season to offer Beiste guidance. And while we're cataloguing Glee's Season 6 queerness, it's also worth noting how quickly New Directions addition Spencer (Marshall Williams) has snagged a same-sex love interest, Alistair (Finneas O'Connell).

At the same time, the sixth season has centered largely on passing the torch to the next generation of New Directions, something it has tried in past seasons with less success. It helps that the members of the new class — including soulful Roderick (Noah Guthrie) and infectiously energetic twins Madison (Laura Dreyfuss) and Mason (Billy Lewis Jr.) — are all quite likable and talented, a fine crop for Rachel (Lea Michele), Kurt, Blaine, and Mr. Schue (Matthew Morrison) to mentor.
