If you're going to invent a made up technology, it should be one that increases the cool factor (things like "warp drives", spaceships, cyborgs, whatever) or or leads to interesting plot points or dilemmas (like time travel, but that's pretty overplayed as well). At least Stargate has a cool looking portal, but as far as I can remember, all it does is take them somewhere, and it doesn't even look cool when they arrive. Like Star Trek but without the cool spaceships.
