Like I said, I very well could be the only one, as everything is personal preference.
While it is nice to have new features added, like Samsung Knox and other apps, I also feel that changing what isn't broken isn't necessary, or the option of having what was previous should at least still be there.
Changes that I don't like:
No more keyboard haptic feedback when typing. (This might actually still be there, but I have yet to find it, and I have gone in and out of pretty much every menu.)
Email app has gone to an all white theme. What was wrong with the dark theme? Dark theme is great for battery life and easy on the eyes!
I also get the vibe that a lot of the icons, widgets, apps, displays, menus are more bubbly. It almost feels like I am using a Tab 3 for Kids model. I don't need some picture of a stupid looking cartoon character as contact picture if that contact doesn't have a picture.
The video app is god awful! bright white background and grainy looking display of all the videos. The previous video app was great. The videos would be playing in the menus while you scrolled through looking for the one you wanted. It was neat.
Photo gallery is just as bad, big and bubbly.
Don't get me wrong, change is good. Getting rid of useful features not so much. Not allowing people to have the option of which feature they want is even worse.
It might be a bit extreme, but I compare the changes here to 4.3 from 4.1.2 to the change the iphone made to iOS7.
Yes I am bitter, but all I really want back is my damn keyboard vibrations. I am freaking terrible at typing on touchscreens, however with the slight vibrations whenever I pressed the keys, I found myself great on the Note 2....
