As question time becomes political theatre, does it still play a vital role in government?

Question Time is, in a sense, the highlight of any day of parliament. It is televised and attracts the attention of the media, providing political leaders with fairly regular public exposure. If parliament is about theatre, this is the headlining act. It is a major opportunity for the government of the day to strut its stuff and for the opposition to embarrass the government. In theory, question time is about accountability. But in practice, it is about politics.
