I think the Goblin was an improvement. The movie suit is actually farly superior to the original comic version.
I personally prefer this

over this

I know it's sad to not see his facial expression because of the helmet, but get over it, omfg. The costume is simply amazing
As for Mr Freeze, I prefer the way he look in The Batman Animated Series. The movie version has nothing to do with the real look of him. It doesnt even ressemble it to the slightest.
I think there is probably another which wasn't metioned, who was a huge disappointment for me, Venom from SM3. He was completly ruined, This how he should have looked like

BIG! Very muscular and BLACK! For god's sake VENOM IS BLACK! NOT **** DARK BLUE-PURPLE-ISH! THE BLUE AROUND HIM IS JUST THE SHADOW!!!! Plus what the hell with the web on his suit? He never had it before, remove it. He was supposed to be over 6'8'' tall and weigh about 450kg, Not about 5'10'' and 70kg, omfg. The jaw wasn't pronounced enough, He looked like an actor with paintjob over his body. This is what my favorite character ever created looked like with an actor with the shape of a 12 year old kid.

The greatest disapointement I have ever seen in my whole life. The worst costume adaptation from a comic book EVER!
