The oni fights are all pretty intense but that the action scenes themselves are not depicted very well. It's hard to tell what's actually happening. People just die, things get destroyed, and basically it's that massacre with Izumi all over again, except this time it's an alien doing it. Same feeling as back then - it's just crazily over-the-top. And again, seemingly zero reaction from the Japanese authorities beyond a couple of cops. So just as before, suspension of disbelief required to enjoy the action. And a twist happens at the end - witnesses!
