yes it's overrated.... it's all about exposure. How you get to the exposure is irrelevant.
It is relevant. These are the ESSENTIAL, creative choices you make in image capture.
Exposure is composed of four variables:
1. f/stop (size of the len's opening)
2. shutter speed (duration sensor is exposed to light)
3. ISO (sensors sensitivity to light--signal is amplified at higher ISOs)
4. The actual exposure. Where do you want your camera's dynamic range to actually record in the scene? There is no "correct" exposure.
Most people know f/stop controls depth of field (how much is in focus), shutter speed controls sharpness/blur of image, ISO determines noise control, and where you want your exposure to hit in a scene will dramatically effect the data collected.
I can take an identical picture of a scene with the same exposure, but have one image with a deep depth of field and everything in sharp focus and another with a shallow depth of field and have an abstract looking blur to parts of the image.
If all you shoot is in automatic mode, you are leaving many of your creative choices arbitrarily up to your camera.

My camera does have more than one manual mode: 'Shutter Priority', 'Aperature Priority' and 'Program'--you are manually selecting one of the variables that you find most important. The other modes on the dial are part of the Automatic mode family: The landscape symbol, portrait symbol, etc.
