It is a pretty good compilation if you don't take the ranking into consideration.
For e.g., Brazil at #93 will make your hair stand. Dracula at #90, Lock, Stock at #75, Chariots of Fire at #63, etc., all are glaring mistakes in terms of ranks, IMO.
But overall, as a list it is a pretty noteworthy project.
