The front of the fusion was taken from the 11-14 mustang so that being said it's the 15 has almost the same front as you car but I don't see you b*tching that your cars grill looks like the fusion.I'm all for something else but throwing the Fusion, Focus, Taurus front fascia onto the next generation mustang is not something new and original. Making the side profile look like a Nissan 370z or Hyundai is not new and original. That's just designer lazy and lack of creativity. The front fascia of the Fusion does look nice, its nice for the Fusion a family sedan. Not nice enough for the iconic mustang. I'm all for moving forward on the exterior design. Just make the design, original and one of a kind as did GM does for the Corvette.
Next the headlight yes the kinda look like the fusion but they also look like the new edge headlights too. When ford redid the fusion they wanted it to look sporty so they took cues from there sports car
