Ratings Critical response Part 1 The review aggregator website
Rotten Tomatoes reported an 88% approval rating for the episode, based on 8 reviews, with an average rating of 8.07/10. Scott Von Doviak of
The A.V. Club noted, "Barry's dark night of the soul unfolds, director
Chad Lowe brings an unsettling, nightmarish quality to the proceedings ... There's some haunting imagery along the way, including a graveyard populated by the casualties of The Flash since the very beginning, but it's the sound design that really gets under the skin: a combination of chimes, whooshing noises, and burbling arcade music straight out of ''
Logan's Run'' unlike anything the series has done before."
Bleeding Cool praised the episode's final climax scene, saying about it "It's such an effective and powerful moment with massive payoff in the final moments of the episode when you realize what has happened." On the subject of the episode,
TVLine said "Team Flash for a fleeting moment thought Barry fended off Ramsey's takeover. But with a final, very unsettling button on his performance, Gustin added just enough coldness to tip off Iris, and us, that the beloved Barry had in fact lost." Chancellor Agard of
Entertainment Weekly noted that in the episode, "[Gustin] flexed even harder in an emotional and torturous episode that saw Barry Allen torn between life and death. This may be one of Gustin's best turns on the show yet." In the review, Agard also praised Gustin's performance in the first part, saying "Gustin's pained performance throughout the entire episode, especially in his confrontation with the Speed Force, definitely helps sell this dark turn, too." In a
Den of Geek review written by Mike Cecchini, the author also praising Gustin's acting, saying "is a showcase for Gustin, allowing him to dig into some of Barry's most human and imperfect thoughts and impulses for almost the entirety of its runtime as he comes to turn with his impending death. Gustin has to carry much of the episode and it's really great work, especially considering how at its heart, this is a simple "battle for our hero's soul" story." Also writing a review for the episode, Craig Byrne of
IGN stated "["Part 1"] starts with a fun sequence picking up exactly where last week's episode left off, giving us a Bloodwork vs. Elongated Man confrontation that features some impressive stretching effects and clever things done with said effects. This is the world that The Flash lives in, and these kinds of confirmations are reminders of the things I like about the show—straight-up superhero action," also saying "Ultimately, this episode gets a lot better when the story starts teeing up what is sure to be next week's more thrilling "Part 2" conclusion"
Screen Rant continued to praise Gustin's performance, calling "The Last Temptation of Barry Allen, Part 1" one of the series' best episodes overall. The writer of the review, Andy Behbakht, said "From every scene where he goes from scared to angry, hopeful to doubtful and, ultimately, determined to broken, Gustin gets to own the spotlight in a new refreshing way. Despite the first part of the
mid-season finale having other strong arcs, Barry's internal battle is what makes the episode stand out as one of ''The Flash's'' strongest hours ever."
Part 2 Rotten Tomatoes reported an 78% approval rating for the episode, based on 9 reviews, with an average rating of 7.78/10.
The A.V. Club praised the two-parter episode's ending, saying "The scene strikes a nostalgic note, with Cisco and Caitlin reminiscing about the early good times before all the doppelgangers and time-travel shenanigans made everything complicated. Maybe this
Crisis On Infinite Earths will serve the purpose the original comics version was supposed to accomplish thirty-five years ago: simplify everything and bring it back to the basics."
Entertainment Weekly compared the episode's tone and themes to the previous one, saying "The episode wastes no time in re-establishing the scary tone from the first part. When Cisco, Iris, and Frost come to in S.T.A.R. Labs, Cisco immediately turns on the Babel Protocol, which he developed in case the Flash ever went bad, and covers the entire building in a forcefield. At the same time, director Michael Nankin employs a few quick shots of terrified Central City citizens running away from Ramsey Bloodwork's zombie army that effectively establish how dire the crisis is and make it feel like a citywide threat." Mike Cecchini, who also wrote the review for the first part of the episode, complemented the dynamics between different character duos, saying "just about as tense as we've ever seen Cisco, and he repeatedly proved Barry's faith in him right. It's no accident that so much of the episode's drama came from Cisco and Iris working together, Barry's two best friends facing a dire threat to the person they love the most. With Caitlin and Frost mostly busy elsewhere, and of course Grant Gustin getting a break from dialogue and big character moments after his showcase in part one, Carlos Valdes and Candice Patton were the real stars of this week's episode, a perfect counterbalance to the first part's deep dive into Barry's brain."
TV Fanatic criticized the Negative Flash storyline, saying "Unfortunately, Negative Flash was a let down. Since ["The Last Temptation of Barry Allen, Part 2"] is the episode before Crisis, we knew Ramsey had to be dealt with quickly. However, Negative Flash did no more than giving us creepy smiles and follow Ramsey around. After all that build-up, you'd think there would be something bigger in store for Negative Flash." Craig Byrne of
IGN criticized the Ramsey Rosso character, saying "With that said, the final Bloodwork vs. Flash confrontation looks very cool, and our last moments with Ramsey Rosso — where Barry gets into his head the same way he had done with Barry and bringing in someone from Ramsey's past—finally gives us that sympathetic feeling missing in the rest of the season. But it's a bit too late, despite my liking Ramamurthy as an actor." Andy Wilson of
Bleeding Cool praised the dynamic and relationships of Barry and Iris in the episode, saying "The success of the episode comes down to the relationship between Barry and Iris (Candice Patton). Patton continues her excellent work as the real glue that binds Team Flash together. There's also a real pathos to her performance, knowing full well these are some of the last hours she will spend with her husband before he disappears." == References ==
