Every now and then we get a movie whose camp appeal is obvious from the moment the concept is unveiled. I recall one day exiting a movie theater, heading down an escalator, when I glided past a massive poster for the 2009 movie Obsessed, starring Beyoncé and Ali Larter (tag line: “I’ll show you crazy!”), and I yelped out loud because I knew exactly what movie I would be getting. I was right, of course, and my friends and I gathered in a darkened theater and watched Queen Bey send that white blonde lady through a table at the end, after Idris Elba was helpless to stop her advances.

We had a similar slam-dunk of a fun time with Jennifer Lopez in The Boy Next Door, a gender-flipped inversion of the tried and true Fatal Attraction premise (honestly, what other Best Picture nominee has served as a more reliable template for camp and schlock?) that promised J. Lo in a series of escalating sexy, dangerous encounters. Though honestly, even we weren’t prepared for the camp value of a first edition of The Iliad.

The premise for the 2017 movie Unforgettable held a similar camp value: ex-wife Katherine Heigl terrorizes husband’s new girlfriend, Rosario Dawson. The tag line — “When love ends, madness begins” — says it all. Heigl plays Tessa, the prototypical ex-wife from hell, formerly married to the suffocatingly dull David (played by Geoff Stults in a very “yes, I could believe that this man thinks owning a brewery would make him interesting” performance). David is newly dating Julia, played by Rosario Dawson. Julia is our protagonist, and we get to experience her encounters with Tessa (whose presence is justified by the daughter she and David share) through Julia’s increasingly horrified POV.

It might not be good, but by golly it should be fun.

So with Unforgettable premiering on HBO tonight, we’ve got five questions to ask to make sure you’re in the right emotional space to receive Katherine Heigl’s blowout, Rosario Dawson’s ode to J. Lo’s Enough, and a whole lotta broken decorative pottery.

Have You Gotten Over Your Katherine Heigl Thing?

This is easily the biggest and most pertinent question facing anyone looking to watch and enjoy Unforgettable is how they’re prepared to deal with their Katherine Heigl feelings. It’s still so strange that such a (no offense intended) B-minus actress would continue to be such a lightning rod for volatile enmity, but here we are. Heigl of course committed the cardinal sin of being an outspoken cast member on a wildly popular TV show — speaking out of turn about cast member Isaiah Washington hurling gay slurs at fellow cast member T.R. Knight helped contribute to the controversy that got Washington fired from Grey’s Anatomy. So public sentiment was already not on her side when she starred in the comedy blockbuster Knocked Up, a film which she not long after called slightly misogynist for the way it treated her character like a humorless scold.

Having successfully pissed off a demographically wide spectrum of fans — Grey’s fans at that show’s peak; Judd Apatow comedy bros — Heigl’s career went in the tank. Within a few years, she’d be all-but-killed-off on Grey’s Anatomy, subject to a series of flop movies like The Ugly Truth and Killers, and reduced to doing TV commercials for cough syrup and cat litter.

It’s been literally ten years since Knocked Up happened. Longer since the Grey’s dustup. Are we all as a society ready to be mature enough to admit that Katherine Heigl…wasn’t exactly wrong? Impolitic, sure, and disloyal to whatever codes of silence require actors to silently fall in line behind their directors/showrunners, yes. But in 2017 can anyone really argue that Judd Apatow movies don’t have a bit of a gender thing re: shewish women? Or that Isaiah Washington shouldn’t have been fired for calling his co-star a faggot? Or that the writing for Heigl’s Grey’s character during the whole “Izzie fucks a ghost” storyline wasn’t embarrassingly bad and not worthy or Emmy consideration? At what point do we give Katherine Heigl at least a modicum of credit for being right?
