This is something that I've always thought about too. Mass Effect was also the thing that got me thinking about it. The first game that is. The aliens just looked so unimaginative to me in that game, and then I slowly realised that these kind of human looking aliens are pretty much everywhere. And it's not just the human like aliens that disappoint me, it's more animalistic types too.
Like why do aliens have to have 4 limbs? Why do their limbs have to have the same number of joints as creatures from Earth? Why do their bodies have to be symmetrical? Why do they need to have a head? Why do their sensory organs have to be in the same place as animals from Earth? Why do they even have to have mouths and teeth? I can't think of any alien in fiction that actually looks truly alien. There's always some kind of familiarity which I think is unnecessary and somewhat unimaginative.
Although I do understand if you have aliens as actual characters in a story they have to look like humans so we can recognise and emote with them. But I still find it annoying that it's not more common for us to see aliens that actually look completely unfamiliar, whether they be characters in the story or merely native creatures.
