Bad Girls Dormitory starts off as any sleazy women prison exploitation movie out there: someone innocent gets jailed, they go to prison with a sadistic warden, corrupt staff and strict picking order between the prisoners. Catfights and topless shower scenes aplenty.
Compared to the other similar sleaze out there, Bad Girls Dormitory landed somewhere in the lower rank, with shoddy production values and with the whole movie looking like it was shot in a backstage of an empty restaurant.
What I did not see coming thought was that in the third act Bad Girls Dormitory turns from below average prison exploitation to actually quite good and entertaining action movie. If the movie had relied only on this aspect, the movie could have been something of a gold nugget instead of the kind of turkey it is.
