Sometimes I'll see a film that's so good that I'll recommend it to friend, and that friend will say "so, Reede, what was it about?" and I'm going round the fucking houses trying to give a detailed synopsis. I also have the tendency to explain things pretty badly and I almost always reveal the sodding ending...completely unintentionally.
These guys have the right idea though, instead of describing their fave movie in detail, they started the #ExplainAFilmPlotBadly hashtag which does exactly what it says on the tin.
