This is a spoiler-free review for Season 1 of What/If. You can stream all 10 episodes on Netflix on Friday, May 24.
If you like soapy noir thrillers, What/If may be an enjoyable, low-stakes binge for you. It goes through the motions, with moody lighting and secrets and twists aplenty. It feels low-budget even though it doesn’t always look it (though it certainly does look it from time to time, too) in that B-movie way many people dig. But if you want something to shock and surprise you, this story isn’t exactly it. To be fair, its leading ladies – Jane Levy and Renee Zellweger – are fantastic and compelling to watch. The frustration of What/If lies in its ability to thread the noir-thriller needle in an engaging enough way: it isn’t campy enough to be fun, or as smart as it thinks it is to be interesting. It just sorta lands with a flimsy thwap.
