The films mentioned were all pre-cgi, and attempts to make available hardware plausible I can live with.
The problem with cgi is that it is fairly convincing, but realism is usually "enhanced" for the benefit of the audience, and it stops being a film and starts being a cartoon. I like cartoons, having gained my cultural background in the New Ritz on Blackpool Golden Mile on Saturday nights when a growing lad, but you could always tell that the laws of physics were being circumvented. CGI "action" movies, on the other hand, are mis-informing the upcoming generation of what is or is not actually possible. Have a look at mythbusters and the ill-founded queries generated on the associated websites.
