A Simple Favor is a surprising dark comedy that is wickedly fun. It’s addictive and thrilling, much like the martinis Emily and Stephanie sip on throughout the movie, which The Guardian pointed out in their review.

“The lip-smacking, acid drops of malice in the latest film from Paul Feig (Bridesmaids) makes this unexpectedly cruel comedy as intoxicating as the mid-afternoon martinis swilled by the two central characters.”

Film critic Robert Ebert was a big fan of Lively’s performance, comparing her to the likes of legendary 1950s actress Julie Christie. “Blake Lively is the reincarnation of Julie Christie in her best work in the 1960s and ’70s: ruthless and charming, 𝓈ℯ𝓍y and detached, a completely destabilizing presence to men and women alike. This is a great role for Lively,” he wrote.

The New York Times admired Emily and Stephanie’s unlikely female friendship, writing: “Mr. Feig handily manages the mood and scene shifts, using regular laughs to brighten the deepening dark. By far his smartest move was to give Ms. Kendrick and Ms. Lively room to create a prickly intimacy for their characters, a bond that’s persuasive enough to push the story through its more forced moments.”

With a cast that has undeniable chemistry along with memorable characters, there’s no reason why you shouldn’t stream A Simple Favor.
