Just looking at the Snake Island scenario, I don't see Russia providing any higher quality information to back up their claims either.
Capturing Snake Island doesn't make much sense for Ukraine, and without a real navy, neither landing on Snake Island nor capturing it would make much sense for Ukraine. I don't think Ukraine really has any plans to capture Snake Island, if anything, for propaganda purposes, and a similar effect could be achieved by constantly bombing the island (and indeed has been achieved)
However, Russia is forced to pay a continuous price for defending Snake Island, and the capture of Snake Island has far more symbolic than tactical value for Russia.
To be fair to the Russian film industry, compared to the rest of the Russian industry, the Russian film industry, especially the level of CG, is definitely not below its Chinese counterparts. Over the years Russia has provided us with many war films with stunning images, and I feel sorry for you if you really missed them.
