In my view this is the finest episode in the entire series.
I think this episode represents the philosophical/spiritual view of the creators of Moral Orel: that one's own intelligence -- not organized religion -- is all that is needed to attain spiritual enlightenment. In "Grounded", Orel finally comes to a very important spiritual realization that one doesn't necessarily need "Church" in order to understand God. This, however, is sadly beaten out of his memory because it does not conform to the religious views of Moralton.
Excellent episode. Excellent (unfairly canceled) series.
Since I can't post this without reaching a minimum word count, the following words are simply filler: one, two, three, four...
