Russell T. Davies definitely had problems and he was not going to please everyone, but his long tenure was very popular and successful from start to finish, and he was essentially a winner. There is a very vocal minority of malcontents who proclaimed his later scripts as supposedly the worst episodes of
Doctor Who ever, but while I can sense strong repetition and signs of encroaching creative burnout, they haven't really won anything tangible and their nerd rage is worrying.
It's healthy to recoginise bullshit and tell the difference between good/bad entertainment, but becoming bitter n' twisted like
Lawrence Miles or
Mike Wong, vanishing up your own backside over a bit of comparatively light sci-fi entertainment like
Doctor Who,
Star Wars, and
Star Trek (that can occasionally reach great heights) is an ultimately unhealthy mindset...
