The human eye does show distinct signs of half-assed-ness.
For instance: The nerves and blood vessles that feed and connect the retina lie on top of it.
This reduces visual acuity by blocking some of the light that enters the eye.
Also, in order to connect to the optic nerve all the nerves and blood vessles have to pass through a hole in the retina which creates a blind spot.

The eye of creatures like the squid on the other hand has the nerves and blood vessles connecting to the backside of the retina resulting in sharper vision and no blind spot.

This is because the invertebrate eye evolved from light-sensitive patches of skin as opposed to the vetebrate eye which evolved from brain tissue.

Another example of the crudeness of design is the wrist.
Look at an X-ray of it and you'll see that it takes two forearm bones and a clump of carpals to give it the same range of motion that a simple ball-and-socket-joint like the hips and shoulders provide.

This indicates either a goofball of a creator or plain old nature making due with what parts are available for adaptation.
