4. Act IV - Who's In Charge Here?
Jerry wants the Grateful Dead to have no leader, no rules... and no purpose. Trouble ensues.

It's the 1980s, and the Dead's fans seek adventure in this "New Lame America" as Garcia calls it.
Runtime: 46 minutes
6. Act VI - It Becomes Everything
Jerry will put up with the adulation until they "come for me with the cross and nails."
Runtime: 58 minutes
Total runtime: 4 hours, 38 minutes
I'm not a Prime member, so I'm not able to watch it; but for those of you with Prime, it should be a treat.
