I love a lot of the stuff that pops up on Cbeebies, as does my 2 yr old boy, but there's also a lot of tat, IMHO.
TAT: shoddy animation, feeble and random storylines, too-silly voices, tedious stereotypes, inaccessible characters:
Waybuloo; Peter Rabbit; Octonauts (should be decent, they're trying really hard, but it's just annoying); Tree Fu Tom; Grandpa In My Pocket; Boj (what the hell is going on?); Balamory; Driver Dan's Story Train; Cloud Babies; Raa Raa; ZingZillas; The Ruddy Tweenies
DECENT: flaws more than overcome by intelligent writing, quality animation, characters you can like, proper stories:
Mike The Knight (despite the stupid dragons); Chuggington; Bob The Builder; Postman Pat (despite stupid Pat); Abney & Teal; Rastamouse; Little Robots; Baby Jake
Three shows on Cbeebies are PROPER QUALITY DECENT: Qpootle; Dinopaws; Timmy Time
Abney & Teal nearly makes it into my PQD list, but not quite.
Thanks.
