The Showa series' later films (1969 - 1974) are cheesy, kid-aimed, re-use footage and have low production values,
Cheesy? Hardly. Out of the
entire Showa era, I can only think of three "cheesy" moments. Godzilla's dance in
Invasion Of The Astro-Monster, Godzilla flying in
Godzilla vs. Hedorah, and Godzilla's tail slide in
Godzilla vs. Megalon. Outside of that, there's really nothing cheesy about the Showa era.
Kid-aimed? Does that explain why every film made after
All Monsters Attack has at least some gore in it? Like the skeletons and visual deaths of people in
Godzilla vs. Hedorah? Or Godzilla's constant bleeding and very visually getting beat up in
vs. Gigan,
vs. Megalon and
vs. MechaGodzilla? Or how about Katsura's sacrifice in
Terror Of MechaGodzilla?
Re-used footage? Only
Godzilla vs. Gigan and
Godzilla vs. Megalon do that, and even
vs. Megalon does it sparingly.
Low production values? Eh, kind of. But as long as the story is plausible, handled well and told in a way that makes it feel like the film takes it's audience seriously, then production values could be as low as possible and you would still get a quality product.
