I watched it last night with my wife. Pretty average but I did watch it all the way through and it was nice that there was some real footage at the end.
Can't remember exactly what the hell I was doing in 2010 but I have no recollection of it at all until it came to my notice a few years ago. Probably fighting my ex-wife for custody of my kids and involved in a financial life or death court battle.
Probably the best value was awakening my interest and getting me googling her and associated people.
There was a 13 year old Dutch girl Laura Dekker planning on a circumnavigation at the same time who was prevented a couple of years earlier by authorities making her a ward of the state but she subsequently overcame that and circumnavigated in a different fashion (still unassisted) but making a number of stops to see the world. Substantially younger than Jessica- not to take away anything from Jessica and a non-stop circumnavigation.
Plan to watch her real doco style movie "Maiden trip" on Prime.
