Of course, the Romeo and Juliet of the 1980s wouldn't end up like Shakespeare's Romeo and Juliet - they would become Macbeth and Lady Macbeth. This is an intriguing and well-made 4-part true-crime documentary about two bookish, uppity Echols scholars who together planned and committed the murder of the girl's parents back in 1985. But who did what? And were they both to blame, or did one manipulate the other?
Unlike what many commenters on here seem to think, the series is actually made by a German crew, not an American one. Which arguably is one of the reasons why Jens speaks German in his new interviews. Another reason is obviously that he now lives in Germany and maybe is no longer that fond of the United States, which he claims are guilty of miscarriage of justice against him.
After watching the series, I don't really have any strong opinions as to who of the two did what, or who is more believeable. And that tells me the producers did a fairly good job in balancing their narrative. The series is not an apologia for Mr. Söring, even if the story he tells himself obviously is just that.
In summary, this is a story of star-crossed love, youthful arrogance/stupidity, and in all probability at least a certain amount of antisocial personality disorder(s).
