I can see why peeps might consider the front end to look 'angry'. To me, it reminds me of a tiger staring and concentrating on prey that has just come into view. It's a "ready to pounce at any second" look. To me, it's a look of power and poise that doesn't mess about, and will trounce you is tested.
OK, maybe a little too much sugar in my morning cuppa tea perhaps. LOL
The front end and the newest tail lamps are the only parts of the newer style that is better than the older generation. The rest of the new-style body says 'pensioner' instead of sport or luxury in my opinion. The newer body has grown on me but I would not trade my 09 for anything aside from the newest Q50, and even then, only if I couldn't find another 09 with very low miles.
