I was a huge fan of the show when I was a kid, so I was really looking forward to this and the 30 for 30 special on American Gladiators that was released to he month prior. The other one spends the majority of the time with John Ferraro (and the elusive DANN "APACHE" CARR) and some of the other Gladiators like Thunder, and more of the competitors (2 SCOOPS!!) that were not in the Netflix doc, and it's a good counterpoint that goes into the actual origins of the show.
A similar tale to pro wrestling, when the injuries start to pile up, nobody wants to loose their spot and then you get PEDs into the mix.
Loved them both, and the original show.
