https://www.imdb.com/title/tt7978638/ , Frat House Massacre is linked to the wrong film on Amazon. This IMDB entry is for the 2018 film, and the one you have linked to on Amazon is a different year and director. Amazon does not currently have this film.
https://www.imdb.com/title/tt4899838/, Haint, has the wrong poster and is incorrectly linked to the poster's video in Amazon. The IMDB film has nothing to do with that instant video nor is the poster correct. C'mon guys! I've submitted this before.
