Cameos
I always see comments making fun of the old man playing "peek a boo" on the bus, but it was really just a cameo of Saito-san in Ju-on: The Grudge, which didn't make sense anyway. Maybe people should see that movie first.
Also, does anyone else think Allison was wearing the blue zip-up hoodie to resemble Izumi in Ju-on? They both acted the same way, wore the same hoodie and met similar fates. Coincidence or not?
Any other cameos?
