I always used to use the excuse for bad CGI as it being a new format and that in years to come (Alien 3, The Relic and countless others at the time) it would get to a point where you couldn't tell the difference. Then we had the Phantom Menace (everyone seemed to float on a landscape that wasn't there because they hadn't quite done the homework on 'grounding a subject' amongst many other things at ILM) and still I would say that one day you'll never be able to tell. Still waiting,,, patiently but to be fair, some of the best use of CGI isn't a monster or a space battle but the subtle things that you didn't realise are CGI like a change in the environment, rolling plains of lush green stuff. I think the problem with CGI is that we as a species know what isn't real when we see it but we accept it and we all talk about how good the CGI was in a movie. Personally I would love to make a movie that is reliant on CGI but no one talks about it, that's the moment I can stop saying one day, you'll never be able to tell!
And I'm tired of the usual excuse for bad CGI being that it didn't fit in with the budget... if that's the case, then when you make a movie, lower your expectations!
Jurrassic Park in my opinion was the first real attempt and they nailed it. The likes of Tron and The Last Starfighter worked because they transcended the CGI by being great movies with bad CGI. Guessing that using marketing campaigns that try to sell you what you know to be rubbish in the first instance really is setting up the providers for a fall... e.g. 'You'll believe a man can fly" and 'Is it real or is it Memorex' No to the first and unsure about the other question as it doesn't really allow for any tolerance in the answer which would be undecided as both are crap'!
The main problem with CGI characters was always the eyes for me... They looked like the eyes of Bruce from Jaws ( the Carcharodon carcharias thingy!) Cold, Dead and souless but years later they would nail this (IMHO) with the work done on Grand Moff Tarkin in Rogue One... but because of this being really good it drew my attention to the lips and how they moved but maybe it was just my brain telling me that this was CGI because Peter Cushing had been dead for years
It will get there but for now Brad Pitt and many others can sleep safe in the knowledge that they will still be required on set.
only my 1 cent worth!
P.S. I used AI to type all this because I'm too busy cooking chicken wings (see below) and confident that AI can do what I need as required but in case it doesn't and purely as a disclaimer... Please bear with me as one day, you'll never be able to tell the difference!
