Margot Robbie in I, Tonya.

Admit it: When Nancy Kerrigan got kneecapped by folks connected to Tonya Harding all those years ago, you just knew there would be a big Hollywood movie about it someday. Well, here it is, starring Margot Robbie as Hardingโ€”and itโ€™s funny, nasty stuff.

Allison Janney is a sinister hoot as Tonyaโ€™s nasty mom, while Robbie proves, weirdly enough, that she was born to play Tonya Harding.

The movie is the subject some post-release controversy, as some people are claiming director Craig Gillespie and writer Steven Rogers tried to turn Harding into some kind of heroโ€”an innocent in the scheme to take Kerrigan out and pave the way for Harding to become the worldโ€™s skating champion. Nah โ€ฆ Harding is not portrayed in a positive light here. Itโ€™s just that her mom is the greater villainโ€”a manipulative, back-stabbing monster who Janney brings to hilarious fruition. As she brow-beats Tonya from her first moments on ice through her Olympic dreams, Janneyโ€™s version of Hardingโ€™s mother is a brash cinematic representation of bad parenting.

Robbie embodies Hardingโ€™s whiny, headstrong persona, staying faithful to the glimpses weโ€™ve gotten of her through the yearsโ€”especially when she challenges some judges giving her bad scores. Gillespie and his crew also do a good job of making it look like Robbie is doing all of the skating. (She isnโ€™t; itโ€™s a combo of Robbie, stunt women and CGI.)

The whole Tonya Harding episode of sports history was surreal and strangeโ€”and thankfully, so is this movie.

I, Tonya is now playing at the Century Theatres at the River and XD (71800 Highway 111; 760- 836-1940).
