Models vs reality
We have all seen umpteen cruddy movies with models (especially in the olden days) and it is my observation that film-makers always seem to neglect one aspect - camera speed. With the video being discussed here, you can see if it was "slow motioned" slightly it would be very much more realistic. You see it with water scenes too - the waves lapping in a model tank would more closely resemble ocean swells if slow motioned. But of course nowadays simulations must be a lot cheaper.
