#150 in 2010
In the poll Mayflies (Part 1) you can see the highest-ranked "mayflies" as of May 2016. Mayflies (Part 2) is about the second highest-ranked "mayflies". Cinderella Man (2005) and Creed (2015) are in both lists because they became the second highest ranked ex-Top 250 movies. The higher ranked Sin City (#75 in 2005) and The Martian (#174 in 2015) have dissapeared from the IMDb Top 250.
Which "mayfly" (ex-Top 250 movie) deserves a come back in the current IMDb Top 250 list?
