I thought the Season 4 finale was really good! It was an epsiode that I felt like really went back to the feeling of the earlier seasons. I love that Wo Fat is in it, however, I wish they did more of that storyline because now I'm left with more questions than answers! And it was too predictable when he escaped... again. No complaints about Chi, he was amazing in this epsiode. I really saw the depth of his character come out in this episode. When Steve let him join Five-0 I was intriguied but not satisfied. I felt it was too predictbale as Steve seems to give anyone who got fired a badge. I hoped that it would end on a cliffhanger, unfortunately it did not. I have high hopes for season 5! I can't wait to see what happens next!
