Well, I'm going to keep watching The Mentalist in hope that they tie up the billion loose ends that there is; but i doubt it.

The actors themselves, I feel, were and are brilliant. Simon Baker can do no wrong in my eyes; he's been the perfect Jane the entire way.
I'd also like to say that I have no problem with the way the last episode was acted, or that T McAllister was RJ. However you can't do the reveal in a 40 minute episode. You can't just leave so many clues like that unanswered. The list - that's just appalling because lets face it, Heller has no idea how RJ knew and he made it up. All the red herrings he has put in the previous series' have no relevance and do not fit in with the end story line.

This is why it doesn't work, because Heller doesn't know the answers himself. It now feels as if he made it up as he went along. I've loved this show for 5 years, and always will, but I will always be disappointed with the ending. You can't build up one of the most loyal fan followings in TV and leave it like that. 

Lets hope he answers the lose ends in the rest of the series or in interviews at least.
