On the back of the terrible season ending for Downton Abbey season one, I watched The Mentalist finale (which ironically I missed last night to watch Downton Abbey... bad bet) and I wanted to say to Julian Fellows: this sir, is how to end a season.
Patrick Jayne has been hunting Red John for ages, so getting some closure while at the same time creating huge suspense for the next season is extremely satisfying while leaving you wanting more (I'm deliberately not including spoilers here). This is just as a season finale should be.
Similarly, Dexter had a great season finale last year when the Trinity Killer left Rita in a literal bloodbath and Dexter's baby on the floor in an eerie deja vu. You're left shivering because there's a sense of resolution accompanied by huge anticipation for what's going to happen next. You're not left feeling cheated.
So take notes Mr Fellowes, and may season two be better.
