I watched that recently too, and enjoyed it a lot more than I expected to.Speaking of Shooter, Claremont, and Lee... Just ran across this tonight on Amazon Prime. I realize I'm 3 years late here, but for anyone else that may not have stumbled upon it, it's an interesting behind the scenes look via interviews (mostly with Claremont and his 2 female editors Ann Nocenti and Louise Simonson, but Shooter as well) of his joining to his leaving Marvel. Never really knew why he ended up leaving, but it makes sense in hindsight.

I think it is free for Prime, and I'm pretty sure it is also free on YouTube.
