Your temp gauge should move. Engine temps vary constantly with conditions and load. So long as its not over heating and the temp drops to normal when not under stress you are fine.
Some temp gauges are just pretty front ends that replace the old dummy lights. They have 3 settings. Cold, just right, or over heating. They trick you into thinking they are real time because the needle moves as it warms up. Because they are really just dummy lights, they look like they never change. Its why a lot of people put real gauges on the "A" pillar. Hook up a scan tool that reads temperature and you'll see what's really happening.
