If something is overhyped then the answer is not to go to the opposite extreme and underestimate them. So far the only successful means od destroying an s400 system is by overloading it and/or using certain types of quasiballistic missiles with clever payloads. All at the right time and in the right locations.
You fundamentally underestimate the s400, our missile systems, and the joint work of our contractors and Ukrainian soldiers that wield these powerful weapons at a sizable tactical level. Both groups are dying in shocking numbers too. This is not a movie and our enemy is no longer just composed of demoralized desert dwellers.
