YMMV / The Simpsons S 8 E 16 Brother From Another Series

• Crosses the Line Twice: Bart praying for God to kill Sideshow Bob? Horrifying. Homer reprimanding Bart by telling him to "do [his] own dirty work?" Hilarious.
• Fanon Discontinuity: Quite a few of Bob's fans prefer to treat this as the unofficial ending of the Sideshow Bob saga, due to it giving the character a more or less satisfying Heel–Face Turn.
• Franchise Original Sin: Introducing Bob's family members to participate in his schemes became a trend after this episode, with varying audience reception. Here, however, Cecil's presence isn't a big issue; his and his brother's voice actors already have strong chemistry thanks to their time on Frasier, allowing for some memorable exchanges. What's more, unlike similar episodes that came before and after, Bob isn't the antagonist for this one. Cecil supersedes him in that role, allowing a different side of Bob's character to shine through. For these reasons, "Brother From Another Series" remains entertaining for many.
• Moral Event Horizon: Cecil Terwilliger absolutely crosses this. He conned his way into building a dam, cut back on the building materials to embezzle the funds, and then tried to kill Bart, Lisa, and his own brother in an attempt to blow up the dam, and the dam floods the town anyway because of the lackluster construction. The only reason no one was killed was because the universe dips into cartoon physics at that point. Cecil doesn't even try to hide behind a Freudian Excuse. When Bob confronts him for Bob's role in stealing Cecil's dream of being Krusty's sidekick, Cecil admits it to be true but the embezzling was mostly done to legitimize his crime.
