I just keep remembering how many complaints about the sedan there were when pics leaked, and how unfounded they ended up being. We already know the front end of the sedan is handsome, and the coupe shares that. That takes care of half the car pretty much. The back end is different, but we knew that, and it isn't all that different from the concept, other than a slightly longer overhang. I think once official pictures are shown it'll be ok.
In my opinion coupe styling isn't everyones cup of tea to begin with. I know quite a few that prefer sedan styling over coupe styling, and that's perfectly fine, to each his own.
I might be weird but, i'd rather have a car with controversial or even jarring styling elements than one that's completely dull and boring and typical. Some of my favorite cars have been regarded as being weirdly styled or shaped (like the veloster). I also think a rear spoiler will help the back end 100% It looks unfinished without one.
