For starters I'm utmost disappointed with the final episode, as I'm sure a lot of us true fans are. I just can't get the people "liking" this episode. And what I can stand less, is the people that crave to see "some action" between Jane and Lisbon, i cringe every time I hear or read the word "Jisbon" (I'm cringing right now as I write it, damn), hell, the last thing I tuned in for watching this show was the romance; in fact, I hoped there will be no romance between them, because that will just destroy the image of the show. This show is not about romance, it's a crime show, it's about a man with phenomenal mind prowess in a search for revenge and justice for the death of his beloved wife and daughter. Don't get me wrong, I don't hate romance or drama, but for god's sake, if you search for romance just go and watch a drama show, there at a crap load of them. But don't watch a serie about serial killers and murders and hope there will be a Romeo and Juliette side story to it, that 's just misplaced and plain stupid.
Sorry for the rant. But understand that I'm on tremendous amount of anger and mixed feelings which the damned last episode just triggered. I even felt sorry for Red John at some point which normally wouldn't even be considered, seing as the man was portrayed in previous seasons... But I guess Heller, ultimately, wanted his super vilain to die as a miserable man, and not live up to the legend that was Red John. By that he destroyed his character, along with ours hopes, and any future prospective that we will ever watch this show again.
Farewell my friends, that was a real pleasure reading your theories and thoughts, some of them were by far better than the dull ending we witnessed.
