I don't like it. It gives the vehicle an over-bite, much like the 91-92 USDM bumpers.
As for "looking different than the millions of other Sentras..."
Where the hell are you seeing millions of Sentras? Outside of Conventions, I see one about every three or four months, and it is almost always a beat-to-shit, run-down, dented, paint-peeling, headliner sagging, steel-wheels, rolling clap-trap of a vehicle. Thee only thing you really need to do to differentiate your Sentra from the "millions of others" is have it clean and with shiny paint. That alone will make it look waaaaaaay different than an average Sentra.
