Kelley doesn’t slow down after the pilot, and he manages to sustain the suspense over 10 hours of well-staged melodrama.

Everything serves to highlight Zellweger’s gloriously goofy performance. As Anne Montgomery, the actress doesn’t so much chew the scenery as absorb it through every pore.

What/If has its longueurs and Levy and Jenner’s lack of chemistry lands like a dead fish. But it roars to life whenever Zellweger is on screen. Tossing her hair and crinkling her eyes, she’s a baroque riot. Her performance alone makes What /If a contender for guilty pleasure of the year.

If you can get past the thorny, sticky dialogue (a big if), What/If has an interesting premise about ostensibly good people doing bad things.

Whatever sizzle there is baked into the premise, in the execution, What/If feels a little too close to "So what?"

What/If transcends junk-food TV and moves into the realm of trans-fat TV. It's definitely bad for you but good luck resisting it. [27 May - 9 Jun 2019, p.13]

What/If basically rips off Indecent Proposal and then admits to doing so, as if that's a clever thing. The series stars a miscast Renée Zellweger as Anne Montgomery. ... [The episodes] are larded with bad writing, dubious editing choices and the kind of weightless fluff that props up most network soap operas.

This show is cheesy, implausible and inconsequential. And waaaay too addictive. Renee elevates it any moment she is on screen.

Even Renee Zellwegger can't save this awful series. It works for the first couple of episodes but then quickly turns ridiculous.

They make reference to it in the show, but this is a blatant rip-off of Indecent Proposal - but with far less heat. I've only seen the first episode. How the hell does this have 10 episodes?

Awful plot and script. A complete waste of my time. They took a 4 episode (or movie) plot and turned it into an excruciating and meaningless experience. PLEASE DO NOT WATCH
