The Exotic Dances of Bettie Page is more for completists, owners of previous docs and movies about the 1950s pin-up girl who has a large fan base that probably has only grown over the years.
Bettie Page: Dark Angel is an all around bad movie, poorly acted and gives no insights into the character and instead is more of a porn film than anything of substance. The lead actress certainly has the look down but the acting is poor, although I can’t blame her too much given the director doesn’t have much going for him.
