This show is nothing less than an absolute landmark in educational TV, and dare I say it, in TV in general. It was like they found the perfect formula: the characters, the timing, the scenery, the lines, the sound effects, and just about everything else. Good old Beakman could talk about *everything* using simple speech, good humour, enthusiasm, always aided by his assistant (originally Josie) and not-exactly-aided by the man in the rat costume, Lester. The three characters completed each other perfectly, and all through the episode, there was not a single second wasted: to every line, there was a perfect reply, and to every question, there was a perfect answer. This is brilliance and talent in their highest forms. Beakman's World can make me laugh harder than any adult comedy show out there can, and I still learn great things with it. It was a shame that Alanna had to leave the series ("Sister Act II", remember that?), and had to be replaced. Liza took herself too seriously, and didn't fit in too well with the other characters. Josie was unbeatable.
And of course, the show was cancelled. I doubt even Beakman could explain us how the execs had the courage to do that.
