Here are links to the "Critical Consensus" tabulations back to 1995, each of which tallies Critic Top Ten lists at the end of a particular year. The list for 2010 is in progress.
From 1995-2002, the early days of the internet, it was strictly a labour of love: Alex Fung (apparently a student at an eastern Canadian university) collected Top Ten lists by various critics, submitted to him by other internet users, and compiled them into a master list. I have been unable to find his compiled charts for 2001 and 2002, but I do have the individual critic top ten lists from which he worked, and have gone some distance toward compiling them. Then in 2003 Movie City News took up the torch, and continue to the present.
I have also worked on a meta-meta-list that would combine the tabulations for the years of the new millenium into one master chart. Big job, so it's not done yet, but here's an in-progress iteration: Critical Consensus, 2000-2008. Hope to finish up that project as we move into 2011.
