I really hated the forehead ridges on Romulans in TNG. As if we, the viewers, were too stupid to tell the difference between Romulans and Vulcans based on attitude, clothing, and plot alone, so we need physical distinction as well. Insulting I thought, and completely destroys the prejudice subplot between Stiles and Spock in 'Balance of Terror' and, by extension, the whole point of them being a breakaway offshoot of the Vulcan race. It was better when we believed they were Vulcans who rejected Surak's teachings, not some distantly related race that's been separated from Vulcan for so long that their foreheads evolved different in the interim.
In any case, I shouldn't complain, because as far as I can tell, Romulans will be Nosferatu from here on out based on what I saw in 'Nemesis' and the new Trek trailer, which is way worse than stupid forehead ridges.
