I don't mind the grille so much. It's a little overwrought, but it could be worse - for one thing, Acura could've tried to slap a beak on it!
My own visual hangup is with the sloping rear fastback; I just don't think it works on a big sedan (same hangup i have with the A7 and, to a lesser degree, the CLS, which at least has RWD proportions). Now, put the fastback look in a smaller package, and it somehow works better; i think the Civic Sedan looks great.
That said, it sounds like the Accord is a gem in all other respects. I'm looking forward to test driving one next month when they come in.
