Some of the reviewers here seem to expect something like Game of Thrones in a children's show, ie something that entertains adults. You have to realise that the audience of this show is infants and toddlers from 6 months to about 4 years. So even five year olds are going to prefer shows more targeted at them.
I feel sympathy for children whose parents expect everything to be educational. Teletubbies is not really supposed to be educational. It is entertainment for littlies, and in that regard it serves its purpose well. The British seem to be very good at shows for young children that are for entertainment purposes only, Americans don't seem to get it.
