People often do not take change too well, especially when it comes to website re-designs. Usually it takes some time to appreciate the new look and feel. It's sort of like adjusting to a new song you heard, or a new car you just saw. At first you might hate it, then it grows on you and becomes normal.
Maybe add some feedback and/or suggestions in the comment section.
I wanted to add a poll but it doesn't seem to be available.
