I give this movie a 5 for entertainment value.. This is the worst acting i have ever seen in a movie.. It contained humorous script and bad directing..
The main female character Minako is raped/"irredeemably betrayed" by her 'owner' and feels it necessary to commit suicide.. yet in the following scenes she strips down nude and jumps in a hot tub with a guy she has only just met.. yes, he WAS her knight in shining armour, but come on! THEN she pursues a sexual relationship with him, and the camera displays her as the 'dominate' one. The 'betrayal' doesn't appear to be affecting her in the slightest.
I feel sorry for the Johnny character, he appears to be second best or third wheel throughout the movie. The main villain has a scar in his left cheek.. of which looks better every time it is seen throughout the film. Continuity seems to be an issue.
As much as this film has bad taste bad acting and bad script, it was quite entertaining for myself, as a viewer, due to the above facts. The unintentional humour is what made me watch through to the end, and possibly even again on a day i need some cheering up.
All in all it was not bad for the era it was filmed in. Cheers.
