Now I'm sure you're thinking, So what, almost every episode puts a spotlight on whoever David is helping. But see, David doesn't really help Mike. Therein lies the key problem: not simply that David isn't the main character, but that he has no connection to the main character. He just chats with Li Sung about Li's imminent death and has a couple of Hulk-outs which feel like a distraction from the plot rather than a contribution to it.
This would still be acceptable if Mike were a decent character with a decent story. But despite a detailed, almost convoluted background, as a character Mike is an utterly cardboard Mary Sue, and a lifeless performance by Rick Springfield only makes him more unbearable.
But the story is the worst part. It asserts that law enforcement is morally equivalent to mob justice; at one point Mike actually states that the police are the villains and the mad bomber they are pursuing (who has already killed four people, including Mike's father) is the victim! This is just the tip of the iceberg, as the script weighs itself down with garbled imitations of Eastern philosophy and chronic disconnect with reality. The climax is so absurd that it's not even laughable.
