'Allo 'Allo is theater of the absurd, and in its absurdity lies its genius. The strength of the show is its bizzare and unrealistic plot twists and happenings. Perhaps the greatest part of the show is its continuity. One cannot simply pick up in the middle, as references to previous episodes are frequent. It is a saga, and a saga must be viewed from beginning to end in order to be understood and appreciated. Otherwise, one would be lost on references to "The Fallen Madonna with the Big Boobies" by Van Klump, the 320+ exploding Christmas Puddings, the Onion Sellers, and other such strance, yet delightfully original, occurances.
Simply put, the show is refreshing, original, and just plain fun.
