I gotta admit him showing up made me laugh. About the movie though, I like the concept . Like what a planet which developed complex lifeforms out of completely different conditions would look like. Sly's god the kaku-man said something that I thought was kind of silly though. He figured that if intelligent life develops it may well be predators. I think it's incredibly important that they are omnivores for one. Agriculture is ESSENTIAL to society and scavenger species like us humans have done well because we are not predators. Screw you kaku-man!
Jaaay for Theoretical science wich has thougt us surprisingly little, but yeah we should totally go to outer space! But if there is nothing out there, it sure is a fucking waste of space xD.
