Mobile Suit SD Gundam Mk III
What they share
Both films are directed by Shinji Takamatsu, Tetsuro Amino, and they sit in Animation / Comedy / Science Fiction territory. If that's the register that drew you to Mobile Suit SD Gundam's Counterattack, the second film will land in a comparable space — through a different lens.
What Mobile Suit SD Gundam Mk III is
A collection of super-deformed Gundam shorts is certainly a thing that exists. The world of Gundam is re-imagined with short, comedic stories. It's probably best enjoyed by people already invested in the franchise.
