It's great given to where we are right now on a technological level, but until we get decent artificial muscles, all biomemetic robots will look like a spastic person having uncontrolled convulsions.
I think you underestimate good engineering. The Festo Smartbird is a good counter example (https://www.festo.com/group/en/cms/10238.htm). I'll agree that we still have a way to go with bipedal robots, but other biomemetric robots (Boston Dynamics) are very impressive these days.
