Excellent production values and solid special effects were squandered on the Korean blockbuster “The Moon,” maybe the dumbest space flight picture since we learned, for certain, that the Moon isn’t made of cheese.

It’s a space disaster movie of the “Apollo 13” “Gravity” variety, and it’s as dumb as a bag of Hyundais.

A few geopolitical points about how the moon might be the subject of conflict over mineral exploitation in the future, prompting a different sort of “space race” are lost in a blur of bad science, melodramatic calamities and performances that drift from xenophobia to jingoism and settle into sentimental slop with the occasional blast of hysteria.

It’s the very embodiment of The Wrong Stuff.

Korea’s second attempt to put men on the moon, one not-sanctioned by an International Space Consortium and condemned by NASA thanks to a launch disaster years before — meets with a similar fate as it approaches the moon.

Solar flares cause system failures, things blow up and an idiotically ill-advised spacewalk kills two of the three astronauts on board.

Wide-eyed, panic-prone, hapless and under-qualified Hwang Seon-woo (Do Kyung-soo) might be stranded in space. As he’s the son of a command module designer who killed himself in shame after that failed previous mission, getting him home to save national and political face is imperative.

He speaks enough English to have a shot at salvation.

“Mayday mayday! Please rescue Me!”

But let’s bring in the previous Cap Com (Sol Kyung-gu), also a command module “architect,” to bring him home. Captain Kim Jae-guk tries to call in favors from his ex, Moon Young, who runs the “Lunar Gateway” space station circling the moon for NASA.

A country of 50 million+ and everybody in this space mess is not just related, but closely related.

Moon, who goes by Jennifer (Kim Hee-ae) amongst her American colleagues, won’t break protocols, even if the endangered astronaut is the son of the designer who killed himself and thus Kim Jae-guk’s late partner.

There’s plenty here that could be taken for comedy — Kim Jae-guk’s comically aborted snowy boar hunt precedes his summons (“I forgot the bullets!” — in Korean with English subtitles), for starters.

But it wasn’t meant to be a comedy, no matter how much Buzz Aldrin laughs.
