I can’t and won’t defend this, because to me there is nothing defendable about this show. Based on the Dandy comics (from the same team who made the Beano) that I also found a source of tedium, I had little interest in this show when it was rerun during my youth and I have even less in it how.
Eric eats a banana and becomes a strong superhero, the central idea is obviously taken from either the Asterix or Popeye cartoons, though it seems to be taken from shorts like Super Rabbit, because the banana power running out was used a lot to try and add some drama to the bland plots. Bananaman is a complete idiot who wouldn’t and frequently didn’t have any real incline as to what was going on if not for the help of Crow, the only character in the whole show with any amount of intelligence.
Despite it faults it was, for some reason, popular here; most likely because it was a home grown cartoon series. The biggest thing is that as far as television series made in Britain go, this was just sandwiched between classic, limited budget, oddball stuff like the Clangers on one side and well made stuff like Count Duckula on the other. The adventures of a fruit based superhero, just don’t compare, heck at least SuperTed cartoon’s were passable if still terrible. This is just badly made, two-dimensional drivel.
