I have a different view. Too often aliens are depicted as flawed/extreme versions of humanity, because apparently we're just that exceptional and awesome.
Quote from Mass Effect:
Look, little girl. When you want a problem shot, ask a turian. When you want a problem talked to death, ask an asari. When you want a new problem, ask a salarian. When you want a problem fixed... ask a human.
Badass right? We tend to think so because we have trouble comprehending something that might in any way be more intelligent, more critical-minded, more creative, more compassionate, more cruel, more innovative, more cunning and more determined than ourselves.
The BE team had a chance to show us something truly alien, both in design and motivations, and make it unlike anything we've ever seen before while also helping us realize just how cosmically insignificant we currently are and how much further we have to go.
I think we're all in for a rude awakening if and when humanity discovers that not only is the greater galactic community
not filled with the sort of naive exotic blue/green-skinned humanoids we'd want to have sex with, or variations of ourselves that just happen to be generally more intelligent but humorless, or stronger but also dumber, etc.
I think it will be interesting when we discover it was never that simple, or that most advances species may regard humanity in about the same way you would regard a gibbon, and everything that humans think would make them special, such as their ingenuity, their leadership skills, their courage, their stubborn nobility, their diplomatic prowess, their lolrandum humor, their genetic diversity, their adaptability, etc., actually pale in comparison to how well other species excel at all of the above and more.
I think if we ever survive long enough as a species, we're going to find out that the universe isn't a carefully balanced RPG, and that certain advanced species just have higher stats all across the board and one of the first lessons we'll have to learn is that we're no more entitled to be the natural born saviors of the galaxy than any other beings. That we'll have to play catch up most of the time and take our chances like everyone else.
