I don't hate this episode like most. I think it's very...average. The two kids finding Batman and dragging him into their basement is a bit of a stretch, but at least it's written well enough.
The last act of the episode bothers me, though. It seems like a cheap HOME ALONE parody, and, the creme de la creme - the Penguin vs. Batman with a screwdriver.
3 stars, tops.
