The kind of lists thrown done as occasional features by popular media. Or on a blog. No I can't remember an example, since those lists are so terrible for anything but tearing apart. It's true that the movies on this list are formally staff favorites, but who is interested in citing their worst taste, instead of their best? Except for a guilty pleasure list, that is. Not even Star Trek (2009) is justified on that basis.
The AFI and Sight & Sound lists are marked by an interest in films that are historically significant but not necessarily alive in popular memory. This is a perfectly valid approach of course. I posted a link to this particular list because it was a rare example of a different approach that wasn't fodder for humor. AFI or Sight & Sound lists would almost certainly include Avatar just for its role in popularizing new 3D tech, for instance.
