It needed another hour to cover more modern programmes, but that's probably out of the question for the next few decades...
I had a similar thought. I just watched it, having DVR'ed it this weekend (and I couldn't watch it Monday night, as I was enthralled by one of the greatest hours of TV of all time).
Was it interesting? Yes. All of the interviewees were genuine characters. I also loved how they brought in one of the wives: "I had no idea what he was doing". And seeing the "give us a few days to prove you're lying to us" bit acted out was almost hilarious.
Was it earth-shattering? No. No real "new" information. Very few "new" stories or anecdotes that haven't been published already. The most interesting part to me was the new OXCART imagery of the DPRK, and the way they explained and illustrated what 1 foot resolution meant was pretty good. I'd personally love to see them release those imagery files. It actually reminded me to look through a pile of documents...and re-discover that I have some BLACK SHIELD imagery of Son Tay.
The main problem I had with the show was that, as Vulcan652 points out, it seemed too short. This could easily have been, and should've been in my mind, a mini-series. All of the stories about life at Groom could've fit an episode, the U-2 and OXCART (it's borderline criminal that TAGBOARD was never mentioned) could've had their own episodes, modern programs could've had an episode, and you could even have done an episode about debunking the myths about Area 51 (the stuff about the Apollo program they did squeeze in there was amusing, as was "oh, sorry, your system is busted, I'm nowhere near that high").
Final verdict: it was an amusing hour of TV to watch, even if they didn't have anything earth-shattering to offer. I'll admit to a degree of bias, given that I'm overly amused by anything dealing with OXCART of the Blackbirds in general, though. But given the access they apparently had to do what they did with it, it could've been so much more. It does make me want to watch for a DVD release, to see if there's anything extra they didn't fit on the air.
