Hi guys.For those who didn't see the leaked episode, I envy you. ;)
What didn't work:
First 15-20 minutes dedicated on how Jane persuades Abbot to let him go and meet Bertram.
He finally meets Bertram, and then it comes out that McAlister is Red John and FAKED his own death.Really?(sweet irony)
Red John made circles around Jane for six+ years, he managed to make a remarkable organization with tremendous power over the Law Enforcement.He was ultra smart, in some cases he made us believe he has psychic powers indeed.
I like this particular actor to be Red John, I just can't stand the way that he was revealed and the way that he died, crying and begging for mercy over his mortal enemy.
Remember Dumar from season 1 finale?He died laughing and saying "Red John".That's how it was meant to be.And that was the episode.So many unanswered questions.
Seriously, I've read theories for RJ's identity in this site that are 1000 times better than this finale.So obvious, so expected with zero  meaning.
