I have a minor grumble ...
I get more than irritated when I'm watching the start of a TV programme ... perhaps there's someone mopping up a lot of spilt red wine ... it could be blood ... and onscreen you see the words "Eight hours earlier ..." and you're whisked back eight hours and you know that some time later you're going to be seeing that red wine or blood being mopped up.
It might be "three days earlier" of course ... or "twenty four hours earlier" ... you get the idea.
Once this device was a novelty but of late it seems to have become overused and in the current season of Southland every episode starts with "X hours earlier ..."
As the Americans would say [apparently] enough already.
