Law and Pauls' endings are my personal guilty pleasure. They are cheesy, cheap and borderline unfunny, but it somehow delivers it every time for me. It's just plainly enjoyable to watch these goofballs being in their element together. Such a contrast to overall serious tone of main cast's endings.
Speaking of Paul, look at how his failing somersault evolved from Tekken 2 to 7. He went from being embarassed by it to accepting and owning it. Now, that's character development. Paul is a good boy. Be like Paul
