I don't find that it looks cheap (the reboot head look, that is), I just find that it looks very perfect. When Robocop took off his helmet in the original, the appearance was important because it wasn't perfect. The rest of his body was very careful, deliberate--it was designed to look perfect. When he takes the helmet off, you see the reality--that it's anything but smooth and perfect. The the joining of man and machine is turbulent, ugly, and painful--not just physically.
That element isn't a part of the new design, which is a little off putting. That said, depending on the plot and themes of the remake, maybe they have a reason for that.
