what i liked- the ending with marge sending lisa to her room, bart and lisa trying to convince homer and marge to take them to Itchy and Scratchy Land, Homer and Bart both going to jail at the park, the ever popular Bort scene (We are out of Bort license plates), the robots going evil, etc.
good episode. it has some very clever and unexpected gags and is a delight. my only complaint is act 3 is like less than 5 minutes long, but that does not detract my score at all. A+
