Worth watching? YES!
This certainly gives insight to what's involved in the lead up and the actual race of the le mans 24hr race (for JOTA at least).
This documentary doesn't go into the technical side of things, more the trials and tribulations.
In my view, it looked like a TV documentary that wasn't up to scratch/couldn't compete with the Top Gear type of audience and was resurrected for the big screen.
It does lack in technical detail, concentrating more on personality than design, quality of engineering, technical driving skill, etc. To think I wasted part of my life watching this
