Barney is awful!!! I'm with you fully on that one SA, my little boy loves him but I refuse to let him watch it (call me cruel, I don't care).
Boobahs are creepy! *shudders*
As for Postman Pat Kye, CBeebies, still play it, they've brought it up to date (with same voice for Pat) and my boys love it, it's one of their favourites along with Fireman Sam and Charlie & Lola (wonderful cartoon, even I'm addicted to that one) - they have good taste!
As for The Tweenies - they scare me now, let alone how I would have felt as a child watching them! Still, again, both my boys seem to like it but it's not their favourite, they soon switch off and go and play with their toys when Tweenies is on!
