Today's 'advanced' special effects? You mean people playing with computers instead of creating real sets, stunts and effects? Today's
special effectsCGI nonsense is an embarrassment.
I'd agree that CGI is overused and misused today - no argument there.
But I challenge anyone to even THINK of making the kinds of exterior shots that the new Battlestar Galactica did but use models and sets. You got a far greater sense of the grandeur and epic scale than anything they did in, say Star Trek: The Next generation (one of the last shows to use model-based effects)
Tron, The Last Starfighter, Babylon-5 - they all paved the way to put things on the screen you couldn't even imagine in the 1970s. But, like any tool, it can be abused..
