While many of the scenes and plot twists on this list still succeed despite their fantastical excesses, one that falls very flat is Season 2's overarching narrative mystery. The pink teddy in the pool, which is shown at the beginning of most of the episodes, enticed viewers throughout the season... That is until its true significance was revealed in one of the least subtle and most overblown "all actions have consequences" metaphors in the history of screenwriting. The pink teddy, it is explained, fell from an airplane that was flying directly above Walt's house that crashed after depressed air traffic controller Don - whose daughter Walt watched die - fails to pay attention to the flight patterns of his charges. If the coincidence of Walt randomly meeting Don in a bar earlier in the season wasn't unrealistic enough, this sequence of events really pushes it. It's straightforward enough to accept that Don is an air traffic controller. Someone has to be! And the fact that he is Jane's father is an established part of the story. But that he was depressed enough to cause a plane to crash - with no-one in a position to prevent him from doing so (don't they have safety measures in these places?) - is pretty crazy, especially given that he really shouldn't have been at work in the first place. The icing on the cake is the fact that the crash happens directly above Walt's home, so that he is left sitting amongst the debris of the crash that he indirectly caused. Ridiculous? Absolutely. Heavy-handed symbolism? No question.
