Look at it this way....If everyone loved the new Challenger there wouldn't be a market for the new Camaro and the sales would dry up on the Mustangs, leaving only other Challengers to race against...and who wants to beat their own...it's not as much fun as beating "the other guy".
Personally I am glad there are those out there that don't care for the Challenger...I don't want everyone driving the same car I do....keep it limited to those who know just how great the new Challenger is......It's not perfect, but it's better than what the other guy is offering....(just my two cents)
