my daughter is addicted to anything on the disney channel,and my youngest son constantly wants thomas the tank engine on,power rangers for my second eldest son and luckily for me mostly footy for my eldest son,if it wernt for him i would never get to watch any 
Out of that lot, Backyardigans. Plus Thomas, Lazytown and Power Rangers. I don't mind any of these to be honest!
My daughter loves Dora but I absolutlely hate it with a passion that has not yet be dreamt of. Closely followed by the marginally (and I mean marginally) lss irritating Diego. I always find a good reason to switch off/switch channel!
