I thought the finale was good, but not great (action wise, anyway. The character stuff was very well done). It was also fairly predictable and kind of played it safe - the good guys all survived and won out against the bad guys, who all died.
I am relieved that they did the smart (and obvious) thing and had it be Burton who killed Rebecca though. He and Kai were the only ones who I would have been satisfied with as her killers, so I'm happy they went in that direction even though it rendered the whole serial killer plot a dead end red herring.
I appreciated the writers' willingness to try new things this year, with time jumps and whatnot, but I think that I ultimately would have rather they had done a regular season of the show: pick up shortly after the events of season 3 and show Hood and Carrie actively pursuing leads on Job/Dalton - rescuing Job before too much time had passed; no Hobo Hood; no Eliza Dushku; no serial killer - the neo nazis should have been the big bads of the season; follow Rebecca's doomed journey linearly instead of in pieces via flashbacks and maybe set up Burton's motivations a little better.
Ah well. It was a solid way to end the series and after the way the rest of the season turned out, I think that was the best we could have hoped for.
Other thoughts:
The scene between Deva and Hood was nice. It felt like an appropriate way to end their side of the story.
Kai and the cartel opening the back of the semi truck only to find Carrie surrounded by dead bodies (and Job on the roof!) was the only moment of the episode where I let out an audible "Yesss!". And then Brock with the rocket launcher blowing shit up! Fuck yeah!
The Hood vs Burton was decent, but also a tad underwhelming. I would have liked a little more back and forth instead of it being super one sided until it suddenly wasn't. Kai being the one to deliver the finishing blow was appropriate though, especially with him holding Burton in his arms like some kind of weird psychotic baby.
Calvin vs Bunker was definitely the best fight scene of the season. It wasn't as ambitious or well directed as Burton vs Nola, but it was still pretty good.
Hood and Carrie's final scene
Job and Sugar's final scene
Suck my tit! (Instead of ....)
I fucking love Job.
How in the fuck did Deva get into college?
Aside from the fact that it's the default storyline for older teenage characters? ¯\_(ツ
