San Francisco Chronicle: February 2019
"If Langen, a rising star in the Bay Area theater scene, most obviously excels in Blaze’s ebullient videos, she’s just as finely calibrated in softer moments, like when Blaze finally tells Gabe she loves him, blurting it out, then repeating the words more quietly, as if to confirm that she actually said them aloud the first time, to test the waters of this new universe where the truth is out in the open. She gives the fleeting moments of tenderness in Blaze’s life a kind of shy warmth, as if she’s aware of how much love she could give but is too scared to unleash it."
"What’s mesmerizing is her enthusiasm and delivery. Langen’s facial muscles seem to inflate, eyes popping, as might an animated character’s. Careening left, then right with each new thought, she almost occupies every corner of her screen at once."

"High school senior Blaze (a wonderfully convincing Isabel Langen) feels hopeless about her future."
- Jean Schiffman

Bay Area Reporter: February 2019
"Seventeen-year-old high school senior Blaze (Isabel Langen, nailing mercurial adolescence) lives in a trailer home"

Splash Magazine: February 2019
"The production and Langen are at their best when Blaze is filming her YouTube channel… Langen’s ability to lose herself in multiple characters at once gives show stopping depth and dimension to her character."

"Isabel Langen, who plays Lotte’s more spirited sister Katja who is transformed into Springsteen’s dancing partner at the concert (a fine meshing of fictional character and real person), has a remarkable and exhilarating monologue about the freedom she felt from the experience and it becomes the play’s richest, most unforgettable hurrah."

San Francisco Chronicle: February 2020
"Perry’s cast members charm... Langen’s Katja breathes fear as if it’s in the air and it’s poisoning her. The only possible end to every conversation for her is a life-or-death dilemma, but her fever takes the form of a dull chronic ache."

San Francisco Chronicle: August 2018
"Cosseted high schooler Alison (Isabel Langen) sees herself as a benevolent princess, befriending woodland creatures, getting courted by suitors, feeding the world’s poor. In Langen’s uproarious rendering, Alison wafts through her charmed world as if always in a ballet recital or giving an acceptance speech, as if she carries a magic wand."

San Francisco Chronicle: March 2018

"There’s #2 (Isabel Langen), who, though more sheltered than her peers — 'We don’t have a TV' — also evinces uncommon maturity. She can issue a genuine apology when she goofs up out of naivete, and she has the empathy to envision and lament someone else’s hardships. The actors, directed by Morgan Green, own their characters with marrow-deep certainty. Langen gives #2 a tremulousness that’s equally capable of bursting into tears or cheering with a stentorian peal."
