What did you probably learn, from space?

We always learn something, though it may not always be useful.  It's like a Liberal Arts degree.

I learned everyone can breathe in a vacuum.  So I don't know why astronauts wear space suits.

I learned that this movie has the best editing ever. You can barely tell that when Star Man picks up a henchman to throw across the room, he's replaced by a mannequin.. Seamless.

I learned that the global whatchamacallit has three powers, not counting the other powers.

What vacuum? There appears to be gale force wind in space. If anything, there's MORE air.

I learned watching the bad guys having 0% chance of hurting an invincible hero, while getting gunned down by said hero who looks like he's enjoying gunning them, down makes me want the bad guys to win.

Also they had far better fashion sense.

I learned there are three more of these nonsense Starman movies and RiffTrax needs to get on with riffing them all.
