The opening credits to 3-2-1 Contact are burned onto my retinas like a brand. I watched so much of this as kid! I really enjoyed the Lisa/Mark/Trini era, but stuck with it through the mid 80's. It's youth science programming like this that made me the man I am today. I guess I should donate to PBS at some point in the future.
I tweeted this a few days ago, but it bears repeating.
