Corrected entry: When Schreber goes with the Strangers to Tune the poor family into the rich family, the Strangers are carrying clothing to dress the family in. If their Tuning is able to change the physical construction of inanimate objects such as buildings, why would they not simply Tune the couple's clothes to something more fitting? Obviously it's not for lack of control - they Tune the table much longer very quickly without knocking over any of the objects on it.
Corrected entry: At the beginning of the film, the water in Murdoch's bath is cloudy. When he puts the fish from the fishbowl (that he accidentally breaks) into the bath, the water is pure and clear. It's unlikely he would have changed the water and he isn't shown doing that.
Corrected entry: The City is perpetually set at night, because the Strangers are allergic to sunlight. Every time the clock strikes midnight in the film is when the Strangers "Tune" the City and change things, etc. After each Tuning, the clock (which is stopped at midnight) continues moving past twelve. There are two problems with this: one, there is no daytime in the six or so hours after midnight, which is to be expected for an average city, like this City is supposed to be (as opposed to some place like Alaska). The other problem is that very little - TOO little - time elapses between Tuning sessions, and surely somebody who didn't have their memory changed between Tunings would find it strange that it was suddenly midnight again (and I mean somebody other than John Murdock). This is a very big flaw in one of the most pivotal aspects of the plot.
Corrected entry: Throughout the movie, the Strangers talk to each other. Yet near the end it is explained that they communicate telepathically, and have a collective consciousness. Then why do they need to talk to each other?
Corrected entry: At the end of the movie during the apocalyptic battle between John Murdoch and The Strangers, Dr. Schreber and all of The Strangers are being sucked into the city but when they cut to the shot of the city moments later Dr. Schreber is the only one visible and there are no Strangers.
