Dont like the graphics.

As long as you do not run the game on low settings, it will look good.
If it is on low, then i agree that the graphics are bad, so that might explain why some find the graphics bad... Only seeing it on low and then thinking them needing.
Of course, there is always some taste in how the game should be rendered, but i think the current graphics are close to perfect.

 

If you're playing the game on low you really shouldn't be complaining about the graphics. Just saying. (Not that anyone would do that, right?)
Also, to WC3 and SC2 being similar graphics wise:

versus.

-sorry for size.
