Seriously Annoying.

I find it incredibly irritating when TV programmes put the names of the actors up on the credits at the start of the programme but cannot be bothered to say which part each is playing.
It is often the case that this is not even remedied at the end or the credits are scrolled down rapidly in mini print.
On occasions TV companies also shrink these to a quarter size in order to give us an advert for programmes yet to come which has already been shown a dozen times!
