I was a little kid when I first heard the words “Ted Bundy.” My dad was watching a news report about him on TV—something about the college students he murdered in Florida—and Dad simply couldn’t believe the guy escaped from custody and committed those crimes.

Even knowing the story of Bundy going into Conversations With a Killer: The Ted Bundy Tapes, it’s mind-boggling what this jackass got away with during his crime spree, and director Joe Berlinger touches upon much of it with his solid, four-part documentary. The series is anchored by Bundy’s own words, recorded by a crafty journalist as he sat on death row awaiting his fate.

This is just part one of Berlinger’s examination of the serial killer; he just wrapped a bio pic on the guy, Extremely Wicked, Shockingly Evil and Vile, starring Zac Efron as Bundy and slated to be released later this year.

The documentary aspires to be the definitive look at the madness this asshole brought upon the world, and it succeeds. It’s not a fun time by any means, but it does the job of informing viewers about the madness and sickness that was Bundy.

Conversations With a Killer: The Ted Bundy Tapes is now streaming on Netflix.
