During True Blood's season 5 finale, I found myself laughing and not because a joke was told--the characters were all over the road. The only real congruent story (I would consider Andy Bellefleur's story if it was the least bit interesting or endearing) throughout the entire season was Alcide's, ending with him becoming the new packmaster. Alcide is finally not moping around and being a wimp; he progressed.
Bill Compton also evolved...in a direction I despise. The writers massacred his character, which was really odd after they made the Bill/Eric relationship so dynamic and engaging. He went from southern gentleman, a vampire with a heart, to a lying, manipulative, crazy monster. Try as they might in future seasons, there is no way to redeem him. Ever. Once a cornerstone of the series, Bill ends the season trying to kill Sam Merlotte, betraying/murdering Salome, threatening/turning on Sookie, and drinking a vial of Lilith's blood, which seems to have reincarnated him as a Vampire God. I suspect he'll be the villain for next season, should I even return to watch. I, like many others, have already decided Bill needs to die, and for me, watching him return from a puddle was the show jumping the shark.
I suppose Eric is now our vampire hero on Sookie's side, moreso than ever, which also ruins the shadiness and selfish pursuits that epitomized his character over the years. At this rate, I wouldn't be surprised if he's eventually murdered or made into a villain, too. Notably, Eric is also the only love interest Sookie has left out of the major three.
The entire Eric/Pam unrequited love story that I always felt was an underlying theme was also dropped as Pam and Tara embraced in a kiss. I guess all that pining and worrying over Eric was just Pam's adoration. And the whole backstory of how she was made, including hints at a relationship, was moot.
Jason Stackhouse is militarized, borderline psychotic, and hellbent on killing vampires, similar to the way Hoyt was in the middle of the season yet more extreme. Oh, and he's also seeing his dead parents after being thrown into a tree. Since the first season, Jason has flipflopped between liking and hating vampires. Sometimes it happens multiple times in a season. In the bonus scene, he considers killing Pam, Tara, Jessica, and Nora (she was the lone character I enjoyed in the finale), but at least Nora is somewhat safe because she recognized the name Warlow--Jason needs her for information.
And where was Warlow? Throughout the entire season we piece together the story behind the death of Sookie's parents, learning it's an old vampire that might even be a fae (I imagine Warlow's blood is what Alcide and his father got hopped up on), then he's never introduced. The story was simply dropped and left unfinished. Cliffhangers like Bill rising out of a pool of a blood that finishes one arch and sets us in a new direction are bearable and expected, but unfinished stories are not; they're just plain frustrating.
What happened to Sam? After his girlfriend exposed shifters to a live national audience, the story ended. We don't know if she died like his brother or how/if they got out of the Authority. Once again, we were left stranded in the middle of a tale. Usually a cliffhangers entail something monumental, a death, return of a character, or major event, but writers tend to give the entire event or get us as close as possible to its conclusion--they don't leave us in the middle of it, during the action, then make us search Youtube for an additional scene. Not cool, HBO.
As for the rest of the characters, most of them hung out at the bar and were used as comedic relief, having had their stories/whatever passed as their stories completed. For a season that started strong, True Blood simply crumbled with each episode. By the finale, the vampire deaths weren't even consistent. Some explode instantly. Others break apart, then explode, and it doesn't seem to matter about their age. The rate of explosion seems to depend on the importance of the character, if you consider Roman, a 500 year old vamp, took a lot longer to die than Russell, a 3,000 year old vamp (I'm still trying to figure out how Eric ran through the light of twelve faeries, which up until that point launched vampires across rooms and meadows, to kill Russell).
To sum it all up, season 5 was inconsistent, at best.
