Critical Reception
“For such an intense, spindly drama, it’s a shame that All Her Fault is a little too brisk in its reveals and reversals. Red herrings are quickly cleared up, and the efficient plotting – driven by determined good guy Detective Alcaras (Michael Peña), whose unwavering competence ensures we’re always on the right track – feels very neat.” – NME
The review notes that the show provides little chance for viewers to engage in their own detective work.
Detective Alcaras's Role
Michael Peña's character, Detective Alcaras, is highlighted for his steady competence and important role in advancing the investigation smoothly.
All Her Fault combines a strong cast with a tightly plotted mystery, though its pacing may limit viewer involvement in the suspense.
