It’s a fantastically over-the-top, drive-in B-movie for the streaming generation.

Adapted apparently quite loosely from Atkins’ Robert B. Parker’s Wonderland, Spenser Confidential has ended up with a genially amusing script expertly tailored to its actors by Sean O’Keefe and the canny veteran Brian Helgeland. And, as smartly cast by the veteran Sheila Jaffe, Spenser Confidential gets spot on performances from a variety of actors, from household names including Alan Arkin to other less celebrated but undeniably talented folks.

You might not pay money to see this in a theater, but you’d watch it on your couch in a second, which is why Netflix makes perfect sense for it. A coda sets up a sequel. There are worse things to look forward to.

Mark Wahlberg and Winston Duke's fun chemistry helps elevate the predictable murder-mystery Spenser Confidential.

The film even pokes fun at itself in the process, fully aware that Spenser Confidential isn’t meant to be taken as seriously as Wahlberg’s last few movies — and just as well, since irreverence plays well on Netflix.
