ghosts

firstly, there's the two lesser known amemiya movies from this era, mirai ninja

and moon over tao

both are definitely lesser known for a reason due to not really having the same kind of production values or moviemaking behind them but elements of that very specific aesthetic are still present for sure

kamen rider black (the original show) is... absolutely not consistent all the way through but at the very least its first handful of episodes are worth trying out as they go very hard direction-wise

almost every godzilla film from 1989 to 2003 or so has something in it that i think would appeal to people who like the 90s amemiya style. in particular i'd say vs. biollante, vs. destoroyah, & vs. megaguirus stand out in my mind

getting away from traditional toku there's 1989's gunhed

1991's hiruko the goblin, which is very zeiram-esque with its normie bumbling male leads trying to deal with this horrible creature (just a note that this one is much more horror focused & contains some fairly intense blood/gore)

jissoji akio's doomed megalopolis/tokyo: the last megalopolis, which is. an unhinged movie that's difficult to follow narratively but in terms of how it looks it might be the closest neighbor to this style

and this is fully getting away from the realm of tokusatsu but i find that kurosawa kiyoshi horror films from this era like pulse & cure honestly tend to have this vibe as well
