It doesn't seem to actually fail at any point though, I've left it going for a really long time, just get unlimited loading.. Which log should I post? Kodi's or is there one generated by netflixbmc? I'll have another crack at it today

You could be having DRM issues (assuming your running a linux ver of kodi) had the issue here and netflix didnt throw up an error just sat there......
try updating chrome stable

Code:

sudo apt-get update
sudo apt-get install google-chrome-stable

current ver is 43.0.2357.130-1 I think
reboot and then from a console type in

Code:

apt-cache policy libnss3

both the Installed and Candidate number's should be the same if not from console type in

Code:

sudo apt-get install  libnss3
