Twitter strag is defending the state of CGI these days No, CGI was always like this, you only remember the good movies

I do agree that most big films today are nowhere as good with it as big films in the past, like the aforementioned Pirates of Caribbean or the first Transformers film were.

I think the problem is that CGI is neglected and treated as a cheap replacement for practical effects, when good CGI is not really that cheap, and not that fast.

Yeah beyond the obvious budget/time constraints, and lack of at the very least practical reference, the biggest issue is the nature of today's movies, their lack of clear direction and film making by committee.

When you're filming 2 actors on a greenscreen with nondescript lighting, where eventually everything apart from actors faces has to be reconstructed from scratch, and probably reworked once or twice, getting good results is hard.

If you are actually decided what the scene should look like, do some or a lot of things practically, both to reduce work and add reference, are decided on lighting - position, intensity, color temp etc., and work with VFX director before any filming starts to make the CG process easier (low light scene, lack of motion, quicker cuts, different framing etc. can hide imperfections), you might get better looking results than a theoretically better CG from more skilled team.
