Sound Like A Bad Thermostat?

I have changed the antifeeze, flushed the system, replaced the water pump, fixed all the leaks. When I am driving, the temp guage always used to remain constant about a third of the way over from cool. Now, the guage goes up a little past the halfway point and then drops when the thermostat opens, goes back up, them drops. I am wondering, is it possible for the thermostat to be sticking enough for it to cause these symptoms, or do they only get stuck all the way open or all the way closed?
