Over Your Ed

Ed being the central focus of this episode pretty much makes it great. His overall clumsiness and lack of social etiquette were shown to be his biggest flaws in this episode, and it showed the Eds trying to help him overcome them (while trying to make a profit off it, of course).

The only problem with it is how at the end the Kanker Sisters (who would pretty much have had no idea what was going on in the first place) showed up out of nowhere, showed that Ed's a fraud, and stole their money with little to no effort, just to put the Eds back to square one. This problem itself turns them into a plot device called "Diabolus Ex Machina", a writing trope that's basically a cheap ploy to ensure things go bad for the protagonists and better for the antagonists, yet I rather my own term for the Kankers as "Cheap Antagonists" where an antagonist has little character and serves no purpose other than to do bad things for no actual reason other than driving the plot.

It wouldn't be much of a problem if it didn't keep showing up in later episodes, but it doesn't really hurt this episode too much. On the upside, this was a much better introduction to the Kankers than in their first appearance since it showed and told exactly who they are. Just listen to the bitter resentment in Tony Sampson's voice when Eddy hissed the name "Kankers" after they just showed up, and you pretty much get the idea of who these girls are. The Kankers' actions thereafter, easily foiling the Eds' plot just to steal their profit pretty much shows why both the Eds and the audience hate these characters.
