None of the advocates of BG3 cinematics have come up with an example of one which exemplifies why cinematics are great or one which the content demonstrates the power of cinematics.
Should that be read as criticism? The obvious explanation is that the OP did not ask for examples. That said, Icelyn gave the example of petting Scratch, and Crimsonrider mentioned the flight of Dame Aylin and the mindflayer transformations. I'm sure that if someone would ask for examples, plenty could be supplied.
Petting Scratch is a good example, I think. There is no dialogue. It just shows you being happy (admittedly with a too stupid grin, but that is a side issue) petting the dog, and the dog with his faithful dog eyes being happy being petted. Now contrast that with a console displaying "You pet the dog."
For me a good example of why cinematics are great is bringing characters to life. For that, you really need to see their faces up close. Jaheira, for example, is a much more developed character (to me) in BG III, just because I can see how she acts and talks. That's decidely different from reading text next to a small portrait.
