The first time I saw this movie (I rented the AB disc) I thought it was godawful. Since I got that AB boxed set with CITY OF THE LIVING DEAD, HELL OF THE LIVING DEAD, LET SLEEPING CORPSES LIE, and HOUSE BY THE CEMETERY, I find myself spinning it every once in a while and enjoying it.
So many people try to dismiss Lenzi as a hack, after some persuasion to watch some of his crime movies these people often change their minds.
I love his gialli (QUITE PLACE TO KILL, OASIS OF FEAR, KNIFE OF ICE, SO SWEET SO PERVERSE, SEVEN BLOODSTAINED ORCHIDS, SPASMO, EYEBALL, etc) and I'm going to start watching his crime movies soon but his horror movies are an uneven bunch. I like NIGHTMARE CITY and HOUSE OF WITCHCRAFT and can even tolerate BLACK DEMONS but GATE OF HELL and HOUSE OF LOST SOULS are the dreck of the dreck (the only good thing in LOST SOULS is when the annoying kid gets killed).
Forgot about NIGHTMARE BEACH/WELCOME TO SPRING BREAK - ick!
