I wasn't wild about the 2011 redesign of the big sedan, which smoothed out the Chrysler 300's classic (if derivative) front end, reflecting what was described at the time as an aftermarket influence. The 2015 tweaks recess the headlights, giving the bumper more presence and returning some of the original's boldness. The big-ass grille handles the rest.
If anything, I wish Chrysler had taken the opportunity to tone down the prominent wheel arches, especially in front where they rise above the character line almost to the hood and recall a Mazda RX-8. It just doesn't work for me. Beyond that, what's great about the 2015 300s, at least as evidenced by three versions here at the show, is that they put not a single foot astray.
