If the James Webb Space Telescope doesn't excite you, you either are dead or not a space-fan.
Weighing over six tons and positiond 1.5 million km from earth (four times the distance from earth to moon) and looking like nothing you've seen before, what is there not to like?
Assuming it makes it into space and then into it's location while still functioning. If we get another fvcked up mirror issue like with Hubble there will be no fixing it. And while NASA does have an occassional bright spot (Mars Science Laboratory - assuming it doesn't crash, JWST, etc.) it's a pale shadow of what it once was. Consider that during the time period that initial picture was taken we had Gemini flying, the USAF was working on the X-20 and MOL, NASA was flying the Saturn I & IB and was deep into design of the Saturn V/Apollo. They'd also begun studies of Saturn V's successor (Nova), were producing the F-1 rocket engine and were in hardware development with the even larger M-1. That's just off the top of my head.
I remember thinking the people at NASA were heroes when I was a kid and expected to be battling Aliens in space ships by now. So much for that. I feel really crappy for my kids who could careless about NASA now. It might as well be the DMV.
