I think you gotta cut apple some slack here. They really delivered on the change we all wanted. I do not like a few icons but not all them. I think some are really nice. Not all the ones I list in dont like are as bad as others. I think Safari is by far the worst.
Icons I like
Message
Phone
Music
Calculator
Compass
Mail
Clock (Although they need to use that swiss borrowed one for sure)
weather
contacts
stocks
videos
Icons I dislike
App Store
iTunes Store
Safari
Camera
Notes
Maps
Settings
Facetime
Calander
passbook
I'm a bit different I like:
Messages, Phone and FaceTime - although they need a different green IMO
Calendar (I really like this even though everyone seems to hate)
Photos (I hated the sunflower icon before)
AppStore and iTunes Store
Clock
Contacts is fine (although hate the side colours)
I would like Passbook if the colors were different
Calculator is acceptable as is compass and stocks
Maps
What I don't like
Settings
Safari
Notes (IMO the worst icon - the app isn't much better and the Mac Notes app is even uglier)
Reminders (It's ok maybe a color change would be better)
Videos (but i think a less harsh gradient would be ok)
Weather - make it live already!
Camera (it's ok but nothing special)
Folders (if it was more transparent it would look good but in most backgrounds it looks solid tray and fugly)
Newsstand
Game centre (I tell a lie notes isn't the ugliest this is!)
