#s 1 and 2 are interesting, but don't hold my attention for long.
#3 could easily be overlooked, but
if thought about is actually quite artistic and very deep ... it is almost like a dissection of what comprises a city ... showing the basic "outside" buildings with their lights and majesty .. and then show a private "inside" look at the lonely people who go in to fill them up, day and night ...
#4 is a home-run, instantly gripping, almost like showing one of those "lonely city people" asking himself,
"What am I doing here?" in this busy, cement-and-plastic world ...
That is my interpretation anyway
