“Broken people healing themselves by providing closure for crime victims” can be an especially effective subgenre if the writing, directing, and casting align — and in Dept. Q, everything gels beautifully.

Undeniably a great detective series and is just as sharp and engrossing as “Slow Horses.

Carl, played by Matthew Goode, is not an easy man to like, let alone love. Yet the show built around him — Dept. Q, a new Netflix series adapted from the Danish noir novels by Jussi Adler-Olsen — turns out to be startlingly likable, and also sad, and funny, and scary, and thrilling.

“Dept. Q” is deeply intense and complex. Its twists and turns don’t always pay off, but overall, the series is a riveting watch.

Dept. Q, which Frank co-created with Chandni Lakhani, boasts a terrific lead performance from Goode, introduces a memorable ensemble cast and even unfurls a compelling mystery, albeit one that probably could have been told with a little more efficiency.

The beauty is that even with all the excess, Dept Q never feels complicated. It’s confident in its simplicity, assuredly propelling you towards a heart-thumping finale. Watching it is rarely hard work.

Dept. Q makes the mystery’s web of lies feel like a window into a larger, well-built world. That quality, coupled with some thoroughly lived-in performances, helps the show stand out in a crowded field.

The Guardian by Lucy Mangan

It is all fantastically well, and rigorously, done. The pacing has a leisurely confidence that some may find a touch slow, but allows for a character-first approach, creating a richness that amply rewards initial patience.

The Times by James Jackson

Dept Q may sound generic, being made by Netflix — or specifically Left Bank, who made royalty sexy with The Crown — but it’s slicker, more expensively done, more visually arresting than your average (even as its stretched over a couple of episodes too many).

The Telegraph by Benji Wilson

Dept. Q is very well done. Goode, more often seen as a buttoned-up toff (in Downton Abbey and The Crown), plays wonderfully well against type as an unbuttoned scruff. His team of misfits are well cast and well-used.
