I don't think it's the technology at all. It's improving all the time and being refined, and people are understanding how to use the technology better.

My theory is that instability in the industry caused by the studios is what's leading to very uneven work. Some of these studios will pay top dollar for big name actors and directors but are willing to have a bunch of random VFX companies from all over the world try to work together to build a coherent vision.
