On the contrary. The beauty of Data was that he was often the most human character on the show. Spiner played him in such a way that you could get glances of the equivalent of emotions. Which is why the emotion chip idea didn't work.
"Does Data have a soul? I don't know that he has. I don't know that I have. But I have got to give him the freedom to explore that question himself."
In Measure of a Man, Data comes very close to expressing grief over the death of Tasha. So there's always a glimmer of emotion, chip or no chip, but the vocal inflection and body language isn't quite there.
What Data has, and a lot of real people don't, though, is a good conscience. He is selfless and always does the right thing. In that respect he's a lot like Spock, despite their overall goal being cross-purposes.
