Those who were infatuated with the very charming first episode of Fox's Glee, which premiered in May, have been anxiously awaiting the show's return this fall. And now, this preview clip emerges, showing Mercedes (Amber Riley) performing "Bust Your Windows." It's catchy and flashy, but I find myself wondering...is it corny enough?

My concern about Glee has always been whether it will be able to maintain its adorably cheesy tone for any period of time. In order to be able to sell a bunch of people nerding out over "Don't Stop Believin'," you have to stay in the zone. It works for an hour, but what about a full season? I worry that this is too straight-faced; that it verges on going for actually cool, instead of geekily cool. Perhaps I'm worrying too much; what do you think?
