Huh? I do not totally understand what you're saying? You're agreeing with me?
It was valid and is valid historically, if you disagree you can quite easily find information on it in film text books, my professors of film and the text books, general film related books, all point to this being the case. It was considered a mistake in the earlier days of cinema.
It was in the 1960 (iirc, totally off the top of my head at 3.30am) with the emergence of the 'New Hollywood' and the times of experimental cinema, coupled with the influx of European art house cinema that started to use it for aesthetic reasons.
I hate no strong feeling either way, I thought it was over used by Abrams in Star Trek (D. Abrams, 2009) but depending on the context, it's fine as an effect.
