The Short Answer

Uncanny Valley. When the CGI of humans is highly stylized (Like in most Pixar movies, Frozen, Tangled, Wreck It Ralph, etc), they look pretty good. But when you try and make a realistic looking person, your mind tends to exaggerate the subtle movements and picks up on all the little things that feel "off" about it. Like, say they decide to make a CGI movie of a giant robot. Have you seen this giant robot in real life? Nope! So your mind has an idea of what a giant robot looks like, but there's some leeway in there. But if they try and make a CGI film like the Polar Express where they completely mimic real-looking humans, you know what a human looks like. You are one. And the leeway for mistakes is really really low.
