Smooth Character Movement?

Unity Engine

Hi Unity Community! Does anyone have any idea how to make this controller script smooth both in movement and rotation? Does the Move() keep the script unable to be controlled smoothly?
js.

function UpdateMoveDirection(){                                                            
    var forward : Vector3 = Camera.main.transform.TransformDirection(Vector3.forward);    
    forward.y = 0;                                                                        
    forward = forward.normalized;                                                        
    var right : Vector3 = Vector3(forward.z, 0, -forward.x);                            
    var vertical : float = Input.GetAxis("Vertical");                                    
    var horizontal : float = Input.GetAxis("Horizontal");                            

    var targetDirection : Vector3 = horizontal * right + vertical * forward;            
    targetDirection *= moveSpeed;

    moveDirection.x = targetDirection.x;                                                
    moveDirection.z = targetDirection.z; 

    if(targetDirection != Vector3.zero){
        var rotation = transform.rotation;
        rotation.SetLookRotation(new Vector3(moveDirection.x,0,moveDirection.z) * Time.deltaTime);
        transform.localRotation = rotation;
    }

    if(canMove)                                                                
        controller.Move(moveDirection * Time.deltaTime);
}

Okay. Having to re-write my script again, the player rotates smoothly now that I used GetAxis with this script, but now the player just looks in the direction of my orbit camera, but like he looks up and downward, which makes him move up wards, and just kinda get stuck in the air. Do I need to add nomalize anywhere?

function UpdateMoveDirection()
{
    var forward : Vector3 = Camera.main.transform.TransformDirection(Vector3.forward);
    var right : Vector3 = Vector3(forward.z, 0, -forward.x);
    var horizontalInput = Input.GetAxis("Horizontal");
    var verticalInput = Input.GetAxis("Vertical");

    var targetDirection = horizontalInput * right + verticalInput * forward;   

    moveDirection = Vector3.RotateTowards(moveDirection, targetDirection, 200 * Mathf.Deg2Rad * Time.deltaTime, 1000);

    var movement = moveDirection * Time.deltaTime * moveSpeed;
    controller.Move(movement);

    if(targetDirection != Vector3.zero)
        transform.rotation = Quaternion.LookRotation(moveDirection);
}
