I just finished watching the first season. It's OK, but it seems to borrow a lot from other series.
It takes the basic premise from
iZombie, substituting electrical connections for snacking on the brains of the recently murdered to find clues in their memories. Most of the memories Kirsten experiences are inexplicably third-person views, whereas
iZombie victim memories were, more logically, first-person.
Stitchers actors familiar to me from other series, are Allison Scagliotti (
Warehouse 13), Salli Richardson-Whitfield (
Eureka) and Oded Fehrl (
Star Trek: Discovery). Stitchers is definitely formulaic, as
@Susan Boulton noted. The only significant ongoing storyline is determining what nefarious purpose beyond solving crimes the stitcher technology may serve.
While the whole seems less than the sum of the parts,
Stitchers is watchable if expectations are not set too high.
