prince of darkness be a bad movie from john carpenter . the whole thing be ridiculous . take the premise and for example . a priest have discover a long hidden canister contain the liquid form of satan himself and or rather his son . say canister have be hidden deep within the basement of an ancient church . upon discover it and say priest decides to call upon physic prof and student to investigate it . soon and the liquid end up in most of the student ( do not ask ) turn then into mindless drone whose only purpose be to aid the son ( say liquid ) into free daddy aka satan . anyway and the whole thing be ludicrous even for sci fi or fantasy or horror . there just isn not any point . carpenter really miss the mark here . with all due respect to the late and great donald pleasence and what be he think . the only redeeming feature of this movie be that it be ( marginally ) less awful than slither and lawnmower man 2 .
