I was really disappointed with McAllister being revealed as Red John. Moreover, they didn't even provide a proper closure on why he did what he did. It was felt so rushed that it seemed liked the writers just wanted to get it over with. Honestly, I thought the Red John (Timothy Carter) revealed in season 4's finale had more class than McAllister. McAlliert's death was such a wimpy one. I'd have expected Red John to have no fear whatsoever going by the hype that was created of him being such a massive serial killer.
Anyhoo, I thought the show would lose it's direction from there, but the biggest surprise is the episodes have now got even better since Jane joined the FBI. I like the new team. What I don't understand is why did they have that mini-story arc with Richard Haibach killing off Ardiles and LaRoche and kidnaping Grace. It was really unnecessary.
