We all know, 50 Shades of Black isn't going to be a good movie but 50 Shades of Grey wasn't good too. So, is there any chance that the Black can top Grey? Which has going to be lower ratings? I'll still going with Black.
shareOne is meant to be a serious romantic drama that is often unintentionally funny. The other is a parody that can make you laugh but has many jokes that miss their mark. So they aren't exactly the same thing. Historically spoofs tend to always receive a lower rating than their dramatic counterparts.
shareThis was better in my opinion.
share50 SHADES OF GREY - 3/10
50 SHADES OF BLACK - 0/10
However, I gave those ratings for different reasons.
