Also, people can say that big picture it looks cheap (colloquial) but looking at those barges in detail, they are clearly not cheap.
I suspect that some people had a preference for something that was more traditional Illuminations with a pyro/country focus versus this screen-based thing. But the reality is that even if they saw the creative for two options, you can't really say which is "better" for something like this until it's built in the real. For example, the creative for the Star Wars fireworks looks good on paper... until the fireworks get moved off-angle and across World Drive instead of literally in your face.
