2. The Warblers
They got their own album and their own uniform, but we want more from the Warblers darn it! Point in fact, I think if Blaine hadn't joined McKinley to be with Kurt at the start of season three, he would have stayed there and we might have actually gotten this spin-off. The Warblers in themselves are a weird, amazing bunch of self-accepting boys but they're rather like a mindless army sometimes - when Blaine was their leader, they were a tolerant peaceful bunch but when evil bitchy Sebastian (as opposed to heroic bitchy Santana, his arch-nemesis) takes control, they become zombies who only show rebellion under extreme circumstances. Who these Warblers really are could make a great side-show for the original Glee club - the faces are recognisable enough that we could start almost rooting for them as their own glee club. Imagine if there was a crossover - the New Directions versus the Warblers. Maybe viewers could vote, the money going to charity, and the viewers themselves shape the season's storylines. That'd be something worth voting for and a pretty cool concept we reckon. We'll be expecting your call, Mr Cowell.
