A duffel bag has just been found abandoned in Times Square. Inside: a naked woman whose memory has been erased, but who is inked head to toe in mysterious tattoo runes, including the name of a top FBI agent, who swiftly decides that national security depends on the two of them teaming up to crack the tattoo code. Thor's Jaimie Alexander is likably vulnerable and earnest as Jane Doe, straining to figure out her past despite her amnesia. Yet the FBI agents are a dull bunch by comparison, especially main man Sullivan Stapleton. Blindspot can only improve when the ink-happy supervillains show up.
