I would like to clear up a few things. First, CGI is an art too. Good CGI is not as easily made as people think. It not cheap either. The main advantage is that it gives the writers/artists ability to create what they envisioned, which could be impossible to realise with stages or miniature models. I prefer good miniature models based SFX to CGI when it comes to film, but CGI itself doesn’t bother me.
It is extremely hard to say it but, bad story/characters/dialogue/acting aside, PT is a revolutionary film and a milestone in film history due to its CGI use. Whether that is a good or bad milestone entirely depends on individual opinion towards the use of CGI in film.
