Make character look at mouse in Unity

So I have this code which should make the character look at the mouse. The character doesn't actually look at the mouse, and I don't know what's the causse.

float CameraDistance = Camera.main.transform.position.y - transform.position.y;
Vector3 WorldPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition);
WorldPoint.z = CameraDistance;

float AngleRad = Mathf.Atan2(WorldPoint.y - transform.position.y, WorldPoint.x - transform.position.x);
float AngleDeg = (180 / Mathf.PI) * AngleRad;

Body.rotation = AngleDeg;

The red dot is where my mouse actually is.

I finally managed to fix it. Here's the code:

Vector3 WorldPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition);

Vector3 Difference = WorldPoint - transform.position;
Difference.Normalize();

float RotationZ = Mathf.Atan2(Difference.y, Difference.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler(0f, 0f, RotationZ - 90);

I had to substract 90 from RotationZ so that the rotation would be accurate to the mouse position.

Instead of doing math operations, you should really look into transform.LookAt(). This method will solve this problem

Also instead of Camera.main, you should use Input.mousePosition

var mousePos = Input.mousePosition;
var wantedPos = Camera.main.ScreenToWorldPoint(new Vector3(mousePos.x, mousePos.y, depth));

Body.LookAt(wantedPos);
