This page shows you the list charts. By default, the movies are ordered by how many times they have been marked as a favorite. However, you can also sort by other information, such as the total number of times it has been marked as a dislike.
Films on the most number of year end top 10 lists: 840 counted.
The top 50 is from http://criticstop10.com/
I am not associated with the site, but compiled the next 50 myself from the Individual Lists page: http://criticstop10.com/2013-individual-lists/
Notes: #51 was on 37 top 10 lists ,while #99 and #100 were on 12 top 10 lists. There were many ties, so I wouldn't look too closely at the order. I feel that this list is a nice tool/reference. Making 12 out of 840 lists isn't too amazing, especially for the widely seen films, but I like finding out which little seen films (many non-American) were acclaimed by critics.
