I don't get the negativity this is getting, I really like it. And you can't say it looks like a Land Rover knock-off anymore. I suspect it's not going to be as popular as the current Explorer because it's RWD and more wagon-like with it's longer and lower profile, but it's pretty sharp and far cooler than it's main rivals (save the Durango). Aviator is more refined but not as dramatic. Compared to Aviator it does have some more visual interest with the rising beltline and stronger character line stretching from the front with a thinner greenhouse. The design on Aviator is more linear, less athletic.
I will hand it to the Ford designers, they took an outstanding design and evolved it further with far more dramatic proportions. I'm still glad this platform managed to survive, I'm shocked we finally have a product from it.
