Up to a point. This is the important caveat. We actually react quite badly to things that are almost human but not quite human enough. The author calls this the uncanny valley.
"The uncanny valley itself is where dwell monsters, in the classic sense of the word. Frankenstein’s creation, the undead, the ingeniously twisted demons of anime and their inspirations from legend and myth, and indeed all the walking terrors and horrors of man’s imagining belong here. In essence, they tend to be warped funhouse-mirror images of humanity.
... Unpleasant surface textures, exaggerated features or proportions, and incongruous, out-of-place additions or inclusions, even body parts that are not directly connected to one another yet move in concert, all reach deep into the primitive part of the human mind to draw forth fear."
