The folks at StageGrade have saved you the trouble of consulting every New York critic's 2010 ten best list and created a mathematically challenging chimera:
We combed critics' Top 10 lists (sources listed below) and assigned points according to whether they ranked shows or not: i.e., a show in the No. 1 slot on a properly ranked Top 10 list received the maximum points, while shows on unranked lists all received equal median points.
Without further ado, the consensus on the best shows in New York in 2010:
Interestingly, quick click-throughs on these titles will reveal that these weren't necessarily the highest-graded [i.e. best reviewed] shows of the year.
Unfortunately, only Merchant, Angels, and La Cage are still running.
