I can’t buy that. Another movie that sums up what I’m talking about perfectly is that Tom Cruise movie about aliens invading us and viruses we’re immune to killing them.
They’re a team of scientists. They should have known better. Hell, since this takes place in the future, I would say anybody that travels from planet to planet would know this.
They still could have gone with a theme of hubris without mixing it with complete stupidity. Like, petting an alien tape worm, especially when it’s hissing at you.
