It takes time to absorb, and invites repeated, obsessive watching. ... Mr. Morris presents a powerful historical argument in the guise of a beguiling work of cinematic art--and vice versa.

On a purely narrative level, Wormwood is consistently gripping and eye-opening, but what truly elevates it to the realm of greatness is Morris’ boundary-pushing storytelling approach. ... Redefining what a documentary can do and be.

Wormwood is not merely a Greatest Hits; it’s a fascinating piece of filmmaking that challenges the form in new ways as it recalls themes its director has been interested in his entire career.

With Wormwood, he [Errol Morris] never promises to wrap up the mystery of Frank Olson’s death in a neat little package. It’s a son’s journey to find closure that makes this absorbing, if not slightly paranoid, series worth your time.

As the vice tightens through the elder Olson’s death and the aftermath, both the narrative drama and, even more, the story of the survivors’ quest for the truth accelerate, making the power of Morris’ distinctive approach fully felt; having come this far, it will be hard for viewers to pull themselves away during the second half of this epic.

A mildly intriguing if somewhat overwrought docu-series for Netflix

Wormwood, ultimately, is a wildly overblown embarrassment to Morris' reputation.

Would of been better as a feature length rather than a docu-series. Interesting enough.

[SPOILER ALERT: This review contains spoilers.]

I was hoping this was going to be a slightly fictionalized, fast-paced dramatization, but no, it's a boring - sorry - documentary that plays out in the '50s and '70s, ugh. Like many books you read, there's just way too much spurious, expository detail included. For me - please get to the point. As such I didn't even make it through ep 1. But see, everyone, EVERYONE knows by now that the federal govt is all about abuse of power instead of governing, that's why there is scandal after scandal after scandal. Now in the early '70s we as a people weren't so jaded yet. But since then we've seen horrible abuses by the DoD, EPA, FBI, CIA, and NSA, as well as the Office of the President with Nixon's Watergate, Reagan's Iran-Contra scandal, and the impeachment of Bill Clinton. So when "Wormwood" is revealing that the CIA did this horrible thing, my response is "tell me something I don't know." It's par for the course. Another decade, another scandal that's made public. Netflix shouldn't have commissioned this, it clearly should've been a PBS documentary.
