I would definitely recommend watching Kong: Through the Hollow Earth and Godzilla: Bringing Nature since you enjoyed this one. Both were great to watch and are sequels to Hakaishin Godzilla : One Vs Many. With Kong: Through the Hollow Earth being more revolved around Kong while Godzilla: Bringing Balance more revolved around Godzilla.
Its kinda shocking how everyone considers shin godzilla to be Fodder when if given time will become unstoppable eventually. Thats his only weakness is needing time and stimulation to survive. Edit: Shin has always had a head at the end of its tail. A human skull
