I am put off by a lot of depictions of aliens as well. I hate the way that most of the time aliens coming from the same planet are the same. I don't mean their image (although sometimes it is), I mean that they all speak the same language, they like the same things, they follow the exact same religion, and so on. As if the entire planet is a single country (or probably a city). You can just look to Earth and see how that model doesn't work. Sure, maybe for some aliens, it could, but when a violent warrior nation somehow manges to cooperate as a single entity, despite being ready to war over anything, it strains the credibility.
That lack of diversity happens too often, if you ask me.
It's impossible to create multiple alien societies each as diverse as our own. Our own cultures have thousands of years of history backing it up, that's why a made up alien society will never feel as credible and authentic as ours. Generalized alien societies are simply one of those things where you have to suspend your disbelief.
Honestly, I'm tired of humanoid aliens period. And if they are humanoid, at least make them like 3 times our size or something.
My God SOOO much this. (I bolded the key part)
Why is it so hard to imagine an advanced (or even non-advanced) alien species that
doesn't look human? I understand the principles of anthropomorphism, but a little creativity would be nice.
I know we don't have a diversity of references with which to base alien designs on (what with never finding alien life. yet.) but for goodness sake, we have millions of species on this planet we could be basing alien designs around. Not just ourselves.
Also, you're right about diversity in fictional alien cultures. In fact, the more alien species you toss into your story, the harder it is to come up with varied back stories to your species.
Though, this isn't always the case. There are some science fiction writers who have taken the time and effort to create incredibly diverse cultures for their alien creations within their stories. Granted, this often only happens with stories that contain a relatively small number of alien species, but still; point stands.

Need some examples really. Mass effect, star wars and halo have some pretty diverse aliens that look different etc.
I think what the OP was getting at wasn't just the look of the creatures, but the lack of culture diversity.
The theoretical concepts behind bi-pedal sentients are pretty much the sole reason most alien life in fiction are depicted with 2 legs and 2 arms.
1. On a practical level, a creature that stands upright with versatile limbs for manipulation and handling, are much more likely to be more intelligent then those that crawl. Why? Well apparently, the only plausible reason for a creature to diminish their raw physical power (higher centre of gravity means less stability, less surface area means less traction, less energy exerted on a charge means less speed/power), is if it uses another trait in place of it. In the case of Sentients, that would be intelligence.
2. A creature with the versatility to manipulate complex objects (eg. a Human with Arms and Hands) are likely to have higher cognitive functions then that of a creature with less versatility (A Dogs Jaws and paws). As a middle ground, the Great Apes having proven to have much higher cognitive functions then any other land mammal on earth but are still a distant second to humans.
3. bi-pedal humanoid creatures, due to serious physical drawbacks are not capable of surviving individually. Any predator that can hunt game of similar weight to the 2 legged creature will have no problems running down and overpowering them. However, this is compensated by hightened intelligence, which includes communication. This basic evolutionary edge that gives 2 or more humans an exponentially greater advantage then one viciously strong predator, is also fundamental to evolving culture. There are minutely different rudimentary cultures to be seen in different packs of great apes of the same species. Scientists theorise that intelligence promotes culture. In other words, culture isn't just a happy accident.
4. Via Culture, people changed from small nomadic pack like structures, to nomadic tribes and settled tribes, the settled tribes evolved into larger communities while absorbing smaller communities via merging or domination, which gradually formed the basis for civilisation. Through Civilisation mankind prospered to where we are now. Theoretically any other sentient life would have to face down the evolutionary challenges in a similar way in order to evolve a culture that transcends it's own physical limitations.
That isn't to say you can't have a 2/3/4 armed, 3/4/9000 legged creature with intelligence, but again there are theories in regards to the number of limbs on a creature, their function and how well they would promote intellectual evolution. As an example, I read somewhere that adding limbs to an evolving species will likely impeded intellectual development because more limbs require more brain power.
So, in short, they look human and have human like cultures, because it's the most plausible way of conveying an intelligent life. It's just easier for writers... that's about it.
Of course, all this is theory... and a lot of it is plain bullshit. Who's to say there isn't a sentient fungus somewhere in the universe. I mean, we have a fungus here on earth that turns Ants into zombies. The universe is weird.
EDIT: Plumb forgot... Orks from the Warhammer 40k universe are sentient fungi. Though they are human like again (but created by a much more advanced sentient race... who I guess are also human like).
