Until the last few, system-destroying weeks, 2020 has been all about comfort. Comfort food, comfy clothes, creature comforts and comforting films and TV shows. Like many, my lockdown comfort viewing has meant revisiting old favourites, a list that includes a presumably higher than average representation of dance movies.

I freaking love dance movies. Even the bad ones. They trigger the little girl in me who dreamed of dancing backup for Janet Jackson, Paula Abdul and Madonna. They’re the guilty pleasures I do not at all feel guilty about. They are to me what action films are to accountants, Marvel movies to meteorologists. They give me life. And jazz hands.

English-speaking dance movies range in style from critically acclaimed balletic masterpieces The Red Shoes, The Turning Point and Black Swan, to quasi-musical dramedies Strictly Ballroom, Billy Elliot and A Chorus Line, to plot-light dance battle porn, Stomp the Yard, Street Dance 3D and the Step Up franchise.

As a 1980s kid, my heart will always belong to the holy trinity of cult favourites Dirty Dancing, Flashdance and Footloose. Of the three, however, only Footloose is currently available on subscription streaming services in Australia. So during isolation, I’ve been all about the early 2000s, a decade as rich in dance films as it was in cat memes and low-rise jeans.

I’m talking Honey, Save the Last Dance, Centre Stage, You Got Served, Magic Mike, Stomp the Yard. I’m talking Jessica Alba, Channing Tatum, Julia Stiles, Mekhi Phifer, Ginuwine and Ne-Yo. (I’m also talking the original Step Up and the technically dance-adjacent Bring it On, but they’re only available to rent or buy on YouTube and Google Play.)

Rewatching these titans of the genre, it struck me that something equal parts terrible and amazing happened to dance movies at the turn of the millennium. They got cheesier. Much, much cheesier. Gone was any pretence of nuance and artistry, replaced wholly by formulas and risk aversion. It’s like at the end of the 1990s, somebody decided the key to box-office success lay in schmaltzy, saturated pageantry. And it worked.

Since long before Y2K, four tropes have formed the plots of most dance films: uptight girl and boy from the wrong side of the tracks dance (and pash) through their differences; small-town wannabe takes a midnight train to the big smoke; person is forbidden from dancing but secretly keeps dancing; down-on-their-luck hip hop crew enter competition possibly judged by Lil’ Kim.

All tropes come complete with a moral or life lesson about prejudice or tenacity or not putting babies in corners. But while their pre-21st century counterparts could be solemn in their sermonising, more recent dance movies make it fun. They may be as corny as an Olsen Twin double-bill but they’re twerking while preaching so it’s OK.

Centre Stage, for example, is crammed so full of the tropes, characters, morals and melodrama synonymous with the genre, it’s canon. Three young ingenues training for the American Ballet grapple with the pressures of leotards, life and love. Each must confront her demons as she dances: unshakeable apathy, a terrible attitude, or a body that refuses to conform to the insane weight standards of professional ballet. There’s a bad boy, a good boy and the overriding message that you should follow your passions and trust your heart. Plus, Sandy “father of Seth” Cohen (Peter Gallagher) is in it so that’s an instant four-star rating.

And from Swan Lake to Snoop Dog, You Got Served delivers street dance glory with extra cheese and a script so bad it’s beautiful. BFFs Elgin and David get into a spot of bother with their friendly neighbourhood crime boss and set their sights on winning the biggest battle their town has ever seen. A rival dance crew, forbidden love and bros-before-ladies betrayal put their bond and their futures to the test, but dancing saves Christmas and everyone learns that friendship is the real winner in the end.

Another great thing about dance movies from 2000 onwards is that they finally brought greater diversity to the genre, at least in terms of race and sexuality. It’s somewhat ironic, considering the importance of dance to so many communities outside the straight, white mainstream. There’s still a long road to full inclusivity, in going beyond stereotypes, casting people with disabilities and across the gender spectrum, but it’s much rarer to only see straight, white people sashaying across the screen.

Dance movies made between 2000 and 2010 and beyond sit comfortably in a proven Venn diagram where cringe meets climax. They’re the perfect example of why we love so-bad-it’s-good cinema and a peppy distraction from all this year has wreaked.
