The Ambilight system is great and there make TV look twice as much fun.
Furthermore, the image always sharp and very vivid of colors.
The sound is good, but I have a super-Hifi Denon which I will mainly use.
The Smart TV features have become "smarter" and more extensive.
All in all, I can recommend the TV much, a good price for a 55 "TV with the extras and super picture.
