I was kind of hoping that there would be a little bit more of an emotional arc in this one. Or at the very least Bart coming off of this with more then just the rational "there's no place like home" at the very end since really that's all he left with in this one. I mean they did good jobs at least sort of hinting at previous plot points in the last couple of eps during the actual story but here any kind of moral (that easily could of been inserted into the last act and a half) kind of goes the wayside making this a weaker episode then the last two by plot alone. Also the humor wasn't nearly as funny. I mean it is good to see Bart acting like a meance but also between this and last time they just seem to be having his menacing be a lot more random then the more percise pranks he use to pull in later seasons. I mean really the whole killer vaccum bot thing was kind of ridicolous and not in an "even funny" ridicolous way and there were a lot of over the top joke and plot set ups (Apu and Lenny pointing out that Homer lost the lottery ticket, the older Bart appearing to marry a female looking milhouse, the whole drive over with the various pop culture refrences including a far too late to ever be funny Macully Culkin Joke, Burns warning Bart of how older siblings will kill you for the inherintence. Which kind of breaks continuity from "Rosebud" which also told of how Burns got wealthy but the show always played loose with Burn's backstory even in the early epsiodes that it wasn't too much a botherence) then should of been. Not that this was a terrible episode. I did like Lenny actually wanting to host a party for all of his friends with his money (which does fit his personality since Lenny is a seemingly nice guy though I would of liked them to try and continue the Lenny and Carl running joke by Lenny wanting to give Carl a special gift and Carl saying something like "you know what people think when you do things like this" or something), Bart getting the driver to laugh at Simon-Bart being strangled, Homer's story at the dinner table, Mihouse saying he has a chance with Bart's new half sister and saying him and Lisa would never happen (line of the ep), Bart and Homer falling in a jacuzzi while rolling down hill and Bart being happy back home and not ending the episode on a joke (I'm glad they're finally not trying to do that with every ep anymore. Guess they finally realized an emotional ending can be nice too). In short the weakest episode of the season so far. Not terrible but the plot and humor could defintley have been tweaked (espically sicne there were few laughs in this one) without even having sacrificed the overall story.
