Bad? BAD! I LOVE the guyver (Bio Booster Armor Rules!!!) Your right Mark Hamil can't act. Best thing he ever did was poke his own eye out in John Carpenter's Body Bags! Ha Ha. The Mangesha Head IS modeled after the guyver. BTW I have both the live action movies Guyver1 and Guyver2 Dark Hero on VHS They ROCK!!!
