Just discovered this show
It's a very interesting show, much different from the shows of today. The family deals with human relations in a very real way, and not everything has a comedic payoff. The show makes you care about the characters, the same way that Mr. Belvedere cares about them, especially the kids, Belvedere is kind of like their conscious, their English Butler version of Jiminy Cricket.
Shows today do not deal with human relations like this, They either trivialize them or go completely overboard. The characters on 'Belvedere' all have their own distinctive personalities, and the show is able to look down as a Parent worrying about their children, or as a child looking out at the World trying to figure it all out.
The two older children deal with the trials and tribulations with the opposite sex that is very dissimilar to the disneyfied versions we see today, they make mistakes and become confused, they embarrass themselves, and get upset and depressed. The Wesley, Belvedere connection is also an important relationship, as the two act like antagonists, but really care about each other. Belvedere becomes Wesley's perfect visualization of a truly grown up adult, while Wesley gives Belvedere that unconditional love that was lacking in his life.
Mr. Belvedere is a lonely man without a family who finds one, and there is something beautiful in the families unconditional love for him, as they take this stranger into their homes and heart.
