Critical reviews "Los Diablos!" received mixed reviews from critics. Myles McNutt of
The A.V. Club gave the episode a "C" grade and wrote, "For better or for worse — just kidding, it's obviously for worse — the rest of the ninth season has been transformed into a litmus test for whether
Shameless has earned this future. And “Los Diablos!” is crippled by those expectations, another inert outing that fails to offer any meaningful story engine to drive interest in these characters." Derek Lawrence of
Entertainment Weekly wrote "With every episode, we get closer to Emmy Rossum's
Shameless departure, and with every episode, I assume things will finally turn around for Fiona, setting the table for a happy goodbye. Well, we're still waiting as Fiona's spiral only worsens when she's fired and eventually arrested. Here's to hoping that she won't get the same sendoff as Ian." David Crow of
Den of Geek gave the episode a 4 star rating out of 5 and wrote "That landing of gallows humor mixed with actual trips to the metaphorical gallows for Fiona made tonight the best episode we've had among 2019's early batch. It portends bad things to come, but it's good to know that that's where
Shameless thrives." Kimberly Ricci of
Uproxx wrote "this week’s “Los Diablos!” installment lightens matters up a lot. Even though Fiona gets arrested by episode's end, the sheer chaotic nature of the episode's last 10 minutes makes up for the depressing tone we've witnessed for the past month of the long-running Showtime series." Christopher Dodson of
Show Snob wrote "In a week of light hearted Hobo Wars and the inevitable doom of Fiona's downfall, Xan's story line was the most pivotal and touching. Well, except that right cross that Fiona used to touch up the new lemonade stand hating neighbor. Fiona's going down faster mentally than that neighbor did physically." Jade Budowski of
Decider wrote "As of now, Emmy Rossum is still set to depart after this season, so this continuing shitshow of Fiona's life these last few episodes doesn't seem to stand any chance of redeeming itself – and it only gets worse during this week's installment, “Los Diablos!”." Paul Dailly of
TV Fanatic gave the episode a 4 star rating out of 5, and wrote, ""Los Diablos!" felt like the
Shameless we know and love. It's slowly getting back to the creative footing it was on a few years ago." == References ==
