There's a few simple rules to living life successfully. For example; if someone asks you if you're a god, you say yes. Slightly less known is this; don't trust an E.T., especially one whose friend you just slaughtered.
I watched Cocoon for the first time when I first got Netflix this spring. It was alright, but there was just one problem for me. When the elderly folks kill one of the aliens and cause the rest of the stranded alien crew to continue to be stranded for several more millennia Brian Dennehy shows an amount of benevolence so ridiculous that it cannot be believed. I think it was a trick and Wilford Brimely and Don Ameche fell for it. I think they were immediately arrested and put on trial when they arrived on Anterea.
