The presentation of Netflix crime docus in general is just hit-or-miss with me. They often bloat them out pretty horribly, making it a 3-4 part series when it really could (should) have been covered in a 90-minute one-off.
And they often spend a bunch of time on shit that you expect to play a key role, only for it to be (at least how they present it) meaningless.
Like they put all this time into the bass player on the boat - yet it went nowhere. They make it seem like the dude is sketchy AF. Yet their direct coverage of him kinda goes nowhere, then ends with two lines on the screen at the end saying the feds cleared him.
They spent a LOT of time talking about her being a lesbian, including interviews with former girlfriends, how she came out, the whole thing of her girlfriend cheating on her, etc. Sure, that's some decent character development, but it ultimately had zilch to do with the story or what happened to her.
Then there was law enforcement. I've seen enough true crime docus to know how often the law enforcement just plain drops the ball (don't investigate thoroughly, don't share resources between depts, have a guilty dude in their possession only to let him go, etc...the Night Stalker docu is a huge example of this). I couldn't tell if law enforcement here was legit hamstrung like they say, or just saving face to cover the fact that they haven't found her, yet.
