Nick’s review published on Letterboxd:
It's sad what money makes you do. Sion Sono will probably make more money from this than from all of his previous masterpieces combined, but after watching Prisoners of the Ghostland, I don't know who he is anymore.
Prisoners of the Ghostland is a farce that's funless and sparkless. Other than stereotypical Japanese iconology throughout, it provides nothing that reminds the audience of the fact that it's a Sion Sono movie. Sexual perversion and excessive gore, two of Sion's most iconic trademarks, are nowhere to be found in this tiring, generic tale of extreme embarrassment and try-hard. Should have known better than to expect anything positive from a Sino/Nic Cage collaboration I guess.
In short, avoid this one. Watch anything else from Sino.
