I don't claim to be one of the great thinkers here but early on into this film I could easily segue into a parallel universe dimension. Steven Hawking, our generations Einstein, says they are very likely...so why make it harder than it is? Thursday I believed in the existence of Vulcan and Spocks mom by Friday evening things changed. You have to make a leap of faith to really enjoy sci-fi otherwise you'll be like the crew at mystery science theater. imo this movie was so good I'm surprised the topic of sustainability hasn't come up yet. Like how can they possibly top this?
