Well someone has been watching Kill Bill

I've never watched Kill Bill though. Good movie?

Really? Well thats exactly what happens at one point in it. Its a good movie, yes.

Guess that means my idea is out. Wouldn't want to be accused of copying Kill Bill.

I have a really hard time taking these criticisms seriously. 
@bozinga - I don't understand the whole "Joel suddenly became stupid" argument. Abby liked and was thankful to Joel. They weren't luring him into a trap- It's nothing like the first game with the scavenger in the street. That scavenger was a "bait". Conversely, Abby wasn't baiting Joel. she actually was about to die. So to Joel, there wouldn't be any reason for suspicion. He just saved her life. I don't see 'this person might turn around and kill me' to be a logical forethought. Perhaps he should have been more cautious, but consider this: Had joel been any other person, he wouldn't have been killed. Logically, the only real argument you can make is that it was stupid to say his own name. However, we've seen in almost any movie or literature on survival, going from difficult conditions to comfortable (living in a town that grew to hundreds within 4 years and are all friends) tends to make people let their guard down. You're entitled to think that Joel's stupidity was just a poorly written plot device, but it's definitely up for debate and you're point is not as singularly convincing as you seem to think. 

Furthermore, the whole setup-confrontation-conclusion argument you brought up hinges on you accurately identifying the story elements. You say that the story is all backwards and mixed up and doesn't make sense. But there are hundreds, if not thousands of revenge stories that are written with a similar type of setup.
-In Kill Bill, you have no idea who Bill is and why he killed the bride or why she wants revenge.
-In The Gladiator, Maximus is an actual war hero and is given heirship to Rome by the terminally ill emperor whose son then kills Maximus' whole family in a bid to steal the throne.
-In Hanna, you have no idea why the government comes and tries to kill her father. all you know is hanna goes bonkers and starts killing everyone. 
-In OldBoy, the story starts of with the lead being kidnapped and tortured and we have no idea why until things play out and you find out the main dude is actually a huge PoS.
-Do I even need to bring up Darth Vader in star Wars being Luke's father? Does anyone really need to see Anakin's life story before I can understand why Vader is so insistent on capturing Luke? 

You say that we need to see Abby's story before we see her kill Joel, but do we really? We PLAYED the first game. We know how bad Joel is. For all I care, the first game IS Abby's exposition. 

Joel is a villain- Despite bonding with him, or liking him, or even agreeing with his actions. Joel is a villain.
When Ellie asks how Joel knew about the trap he responds, "I've been on both sides". He's trapped and killed innocent people EVEN BEFORE he ever meets Ellie.  Regardless of making ends meet or surviving, we also see his moral failures towards the end, wherein Joel offers just go back home and Ellie replies,
"if I don't go through with this, then everything we've done.. everyone we've lost...it's all for nothing"
Joel then kills the entire hospital, the resistance, Marlene, and condemns humanity. Joel betrays and dishonors everyone you met in the game, all bc he wants to keep Ellie to himself.

TLOU is great game specifically due to how the narrative induces compassion for Joel's journey.... If you honestly need more exposition to understand Abby's motives at that part of the game, then I'm afraid to say that it's pretty obvious why. You didn't understand the last of us. 

Playing through it myself, I was also surprised that Abby was out for revenge. I wrongly assumed that since she was kind of normal and I had been playing as her, she would be a good guy. What's more interesting is that even now, I can't think of a reason to say Abby was wrong to kill Joel. AFAIK, Abby's story begins 4 years earlier when Joel kills her father. AFAIK, Abby could actually be the hero of her own story, climaxing with her killing the target of her vengeance. If you think about it, Ellie's journey in TLOU2 is Abby's exposition. Abby is just Ellie from the future, if you understand my meaning. The difference being that Abby didn't spare her target and Ellie does. 

The way you described how the story should have been written, we should have played out an entire story of Abby's revenge and then played out Ellie's revenge. Honestly, I can't think of anything more tedious or boring than having to play out the same plot twice.

or maybe you should pursue a career in film. We definitely need another Quentin Tarantino.

I would say that at the hospital he wasn't at his best mental state and he also knew that if anyone was left alive that knew about Ellie she was going to be hunt. And sure after all the kill he done in the past he wouldn't have issue killing a few more.

Anyway even criminals have loved ones and can act kind. And he being able to sympatize and have real care and love eliminates him being a sociopath.

I'm not saying Joel definitely is a sociopath, but I want to correct you on something. Joel at no point sympathizes with Ellie. Ellie made the decision to finish the job and Joel took that from her. That is the opposite of sympathy and empathy. To empathize and sympathize is to feel what someone is feeling. By making the decision for her against her own wishes, he demonstrates a clear lack of empathy. Saying thatvthat Joel acts out of love overlooks the fact that sociopaths do in fact care for things, but the things they possess. When a sociopath is sad that a friend or pet dies, they aren't sad because that person will never experience life again, nor feel for those that are also hurt. They are sad because they lost their possession.

Id even suggest this lack of empathy is further evidenced in the scene where Joel gives bill his partners suicide note. I think that while some might say it was the right thing to do, it can't be ignored that the letter was a devastating blow that didn't necessarily need to be spelled out.
