The only things I found bad about the old Heavy Rain teaser was that the girls voice didn't seem to match well with her in-game character, or maybe that was just me. Also, the lip-sync technology they used was kind of weird in that it didn't match the girl's voice and looked kind of weird.
Actually, now that we mention the game, I remember reading an IGN interview about Heavy Rain after that year's E3. The developers even noted that the lip-syncing was weird.
