Through no fault of DePatie-Freleng, the character of the Human Torch couldn't be included in this series because he'd already been optioned for a film project which, at the time, didn't come to fruition. Instead, marvel legend Stan Lee created Herbie the Robot, voiced by the multi-talented Frank Welker, Megatron in the original Transformers. Although some fans reacted badly to the new character, for those who were just small children at the time, Herbie was perfect for us. His longevity has since been assured in Marvel Comics where he now serves as a sidekick to Franklin Richards, son of Mr & Mrs Fantastic.
As a small child many years ago, this series was a great introduction for me to the World of Marvel Comics. Guest characters include Magneto, Blastarr, Doctor Doom, The Inhumans, and Skrulls to name but a few. The stories and characters have an innocence about them which is missing from modern television, and the emphasis is always on fun... even when Herbie and Ben are squabbling the way best friends tend to.
And if the cell-animation seems simple and basic by today's standards, where cgi seems to rule the roost, then let us not forget that DePatie-Freleng actually helped out with the special effects on the original legendary Star wars film.
In short, Fantastic Four (1978) is fantastic for kids... and also for grown-ups who want to remember the good ol' days!
