Were to start? For one thing, it is extremely funny. Believe me, once your kids see this show, they will be able to distinguish true comedy from the crap that people call comedy today, especially on Disney Channel (e.g. Sonny With A Chance, Hannah Montana, The Suite Life On Deck, etc.). Another contributing factor is how well the acting is. All four actors are brilliant and the chemistry is definitely there. What I mean is that a lot of things that happen or have to do with the show also happen in real life. For example Lucille Ball and Desi Arnaz are married in real life, so the love on the show is real. Also, in the show Ethel and Fred aren't exactly fans of each other, but that didn't take much acting because Vivian Vance and William Frawley hated each other in real life. Another plus is that in a lot of episodes there is singing, especially from Desi Arnaz (who is a very talented singer by the way). So all in all, this show is one of the greatest, if not the best, TV show of all time.
