The plots are also extremely illogical and incoherent. I think though the greatest failure is in character development.

Rewatching it recently I felt like it was a drama about a really bad boss. Martin Landau's character is a terrible leader: shouty, over emotional, inclined to sudden bouts of despair, micromanaging.

It's obviously a great pity because as everyone agrees it's a beautiful show with a top notch theme.
