Two major ones that come to mind are Pacific Rim and Avengers Infinity War.
Pacific Rim's fight scenes are all amazing. Each one is unique, memorable, exciting, and engaging. All of the robot and monster designs are original and creative. Its one of the few movies where right after it ended, my first thought was "I cannot wait for the squeal!" If only that sequel actually lived up to the excitement.
Infinity War is nonstop climax. It never lets up on either comedy or action. Nothing drags on, and nothing feels rushed.Its just great. But the last five to ten minutes will kill you.
