DS tends to go in cycles, but this time it's even more pronounced because a few Corrie fans are stirring the pot, spending a lot of time going on about Eastenders not being very good. But to be fair to them, Walford Web also has a lot of complaints about the show at the moment.
I haven't really seen Eastenders as being what it should be in a number of years, so I'm still enjoying the show more than I did when Santer was around, and the ratings are holding up, so there's that.
I do think a lot of people are so into the idea that death is what a show needs -- there was a lot of heavy focus at DS on the pub fire, and a lot of anger when no one died (I thought that was a brave choice). Now Corrie is killing off a few characters, so, even if it's being done clumsily, has been telegraphed for months, and for no real reason other than shock value, that means Corrie gets the hype.
