I collected over 25 lists of the Best Movies/Films of 2018 from the Internet, magazines and newspapers and combined them into one meta-list. Here are the results: all the movies on three or more of the original source lists, organized by rank (that is, with the movies on the most lists at the top).
PLEASE NOTE: These are not my personal opinions. I have not seen all these movies. But if I have seen a film, I have included my 1-10 rating.
