First and foremost, Preacher did not end as I expected it to be. It has less violence and blood than the previous concluding arcs. The final setpiece is rather subdued and "quiet", save for a couple of explosions and gunshots. Though it is not the end I have expected, Garth Ennis has ended it in the best way Preacher could have possibly ended. And surprisingly, the ending has a heart and full of hope. Thus in a few words, I try to summarize what I felt about the ending, and please pardon my language: 
 "And they fuck*ng lived fuckin*ly happily ever after. So f*ck you and I love you, Preacher has ended." 
 Alamo, the last volume is way more grounded and personal than the other volumes of Preacher. In fact, it is those personal grudges and motivations that drove all the main characters in doing what they ought to do. All the religious political BS and the "confronting god" thing for me just took a backseat in this last arc. 
 If there is one negative thing I can add in this review, it was really Jesse Custer's plan. It may be brilliant and feasible from the preacher's point of view, but it is anti-climatic and a eenie-bit of a letdown from a reader's point of view. I mean, that has got to be the Jesse's main mission in the whole series, a sort of genesis versus god fight ala-Mortal Kombat right? 
 As for the main series, Genesis really, really felt to be hugely underused and underdeveloped. The demon-angel lovechild didn't not really lived up to its full potential and the power of the Word being not as formidable and dangerous as it should have been. And what ultimately happened to Genesis was too convenient. Its fate was inevitable, but yet too convenient. 
 Arseface's charm was felt until the conclusion of his story, but he could have been part of a larger scheme. But this is just nitpicking though. He is anyway the Hodor of the story. Herr Starr's fate was also inevitable, but Ennis made sure that it was helluva fun to see him being laughed at which is a sort of guilty pleasure feeling. The Saint of Killer's on the other hand got his dream of revenge fulfilled, though I doubt if the satisfaction will last forever. This kinda reminds me of Kratos. 
 As for Jesse, Cass and Tulip, our three main characters, I will let you read what ultimately happened to them. 
 For me, Preacher may not top the feeling I got from Scalped for a big chunk of the series but Ennis certainly nailed a better ending than Jason Aaron. It was funny as hell and a ridiculously fun trip, being with Jesse and co. Thank you Ennis, Fabry and Dillon for giving us such a great read!
