Always better for children to read rubbish than watch rubbish in my view. There are a lot of criticisms that can be laid at EB's door, but it's not actually all bad - when it's bad, it's beyond awful, when it isn't it's...ok, or at least was if you were the age group it was aimed at in the rough time frames it was origninally published in.
I think it depends a lot whether you read them as a developing reader - if you did they were ok. They weren't books that you would generally keep reading though.
For the record, I do actually hate her works but know that there are others that still like them.
I read her books avidly for a short period but can't revisit them at all, unlike authors like Dahl, Susan Cooper, Alan Garner and John Christopher.
