What I really like about Khan Academy is that Sal takes away all the magic. The limit as x approaches 0 of sinx/x isn't 1 because "that's the formula," it's because (insert Sal's 15 minute proof showing the graphs and allowing you to intuit the result).

In contrast, I just watched the first two lessons of this series and so far it feels like a lot of magic. It's just a "rule" of strictly dominated strategies that each of player 2's middle column values are larger than their end column values, so we can eliminate the whole column. Why is this? What do those values represent?

For anyone who has watched more of the videos, does the series improve in this regard?
