I personally love how they look. No need for cars to have a grill. The aesthetic is sleek and modern.
However I felt the shape of the front nose on the original Model 3 unveil was aesthetically "incorrect" - like a streamline with an anomaly. It wasn't about grill or no grill, but wrong curvature (subjective of course, we can agree to disagree).
These new photos show a much improved nose shape.
