Re: In the film, Drax's shuttles dock with a space station
"Drax in the film is (like Musk) concerned about a catastrophe wiping out human civilization on Earth."
Um, in the movie Drax is about to cause * a catastrophe, namely wiping out all human life on Earth using nerve gas. Because he seems to have a god complex.
IIRC, in the book Drax wants to destroy London with a nuclear armed rocket, but is crushed to death under some giant bog rolls or something.
So I guess we'll have to wait and see where this is all going.
* Okay, technically planning something could sorta qualify as "being concerned about something", I'll give you that.
