I submitted a suggestion that we can watch The Goonies, a movie from 1985 about a group of friends. Today, I think shows like Stranger Things try to replicate that feeling of growing up in the 1980s but it isn’t the same as watching something that came out during that time period.
Another thing we could do is compare a 1980s movie to a modern movie that takes place in the 1980s. It might be fun to discuss the differences. However, I am not sure if there will be a big enough difference between the two to actually have a discussion about it.
