One character's POV is very exciting and is moving quickly to the climatic moment where Johnny is confronting the thugs on his street. But then there's Jackie's POV: Her boring life and the little things she does to liven it up, are truly flat lining, and isn't going anywhere.
The pace of the first story is full of drama, life and crisp.
The second is boring and slow.
When your stories climax at different times or one story drags down the other, it is time to whip it up. It is best to have POV sections escalate concurrently and reach their climax at the same time. And the POV should always move the story forward.
