That and the same kind of intrigue stories and same characters.
I mean there is allways a Shawn in one way or the other
TWD lost its pace in season 2 allready. Season 3 was nice with the Governor but way too stretched.
Im surprised that Im not totally bored with Black Sails allready. In the last season it allmost got to this point but the new one started off pretty well.
Btw Im a fan of Doctor Who so I dont think standalone episodes are a problem, they just need to decide what they want to do.
TWD had too many of those in my opinion or at least those werent connected too well.
