Hellbound: Hellraiser II (1988)

Plot hole: When the policeman asks Kirsty at the beginning who came when she solved the box she says the Cenobites; she had no way of knowing what they were called. Frank only told Julia; Kirsty didn't hear it anywhere and the Cenobites themselves didn't tell her either.

Plot hole: The mover shouldn't have been pulled into the mattress because he didn't bleed onto it, which is what was required before, for Julia to come back.
