These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Godzilla vs. Gigan
Awesome Music: While the music was indeed lifted from other sources, one cannot deny that the editors were very wise with the selections that they chose, since this would be the last film until Godzilla vs. Mechagodzilla II to feature Godzilla's theme as it was heard in Mothra vs. Godzilla. The music from Mitsubishi Pavilion is also very wonderful and when it's used during Anguirus's friendship moment, it really strikes a chord.
Narm Charm: Like many Showa-era Godzilla movies, this one is most definitely not a cinematic masterpiece but it has its moments. Fans really seemed to like Gigan himself, and the actual climatic battle (when its not using Stock Footage) has some memorable moments such as Gigan notably being the first villain to make Godzilla bleed and Angurius's Friendship Moment.
