I found the end oddly satisfying, in fact, one of the more satisfying series finales that I've seen. I think it would have been cheap for either Will or Hannibal to deal the other a deathblow after that thrilling finishing of Dolarhyde.
Well done to Fuller, he built up this bizarre relationship between the 2 and follow throughed with an apt, if admittedly disturbing, climax.
Brilliant ending to a show that lost its way a bit in the final season.
Or they could've just stuck with the perfect ending of Red Dragon. Will is maimed, Hannibal has essentially left his mark. Will pays the price for his hubris of getting back in and is a left a broken man.
Like I said, this ending felt like bad fan fiction. We are given no payoff for several dangling plot points (Will's family, Jack, Alana, Dolarhyde's backstory, what pushed him over the edge with Reba, etc). All ignored. Instead we get what is essentially bad slash writing. "This is all I ever wanted for you Will....for
us."

Give me a break. This **** would not pass for good dialogue in a cheesy romance novel. "BUT TEH FUELLER WROTE IT AND ITS ART!" so it gets a pass? Nuh uh.
Also, can I point something out? WILL DIDN'T CATCH DOLARHYDE! You know, in the book, Will actually deduces his identity by following clues. Did anyone notice that didn't happen? The entire Red Dragon investigation is Will going to the victim's house once, flirting with Hannibal, setting up a plot (that he apparently knew would result in Chilton's maiming, even though we have no indication of such...but Hannibal says so and apparently it furthers their pseudo-romance, so whatever), and then having moody conversations with Gillian Anderson (whose character serves no purpose) until Dolarhyde snaps, tries to kill Reba, and that results in everyone just finding out who he is. So the FBI brought Will back to sit with his thumb up his ass and do nothing apparently. Come to think of it, why do they EVER consult with Will? He only learned who the Chesapeake Ripper was because he revealed himself to Will (and then framed him). Will only caught Hobbes because Hannibal told him who it was. Will is a pretty ****** investigator, when you think about it.
This whole arc was just sloppily written. It had no real direction (which is ironic considering it is the one arc of the series that the writers had laid out for them). And all it leads up to is Will, apparently acknowledging his love for Lecter (despite all evidence to the contrary) and then committing suicide. Yawn.
