Corrected entry: In the scene where Sarah confronts the guards to the two doors, the one guard who presents the rules either has to always tell the truth (for the rules to be true) or both of the guards are liars (which negates the rules entirely), in that case Sarah never really stood a chance even with her logical solution.

Correction: This is not a mistake, but a good observation nonetheless. It proves that the guard she is talking to is the one who always tells the truth, and so she COULD have solved the puzzle a lot easier. Unfortunately, she does not catch this, and has to try the old-fashioned way.
