The anime finale was a little better since they spent most of it on the Rize dream sequence and it let up to OP Kaneki. It's still a horrible rushed anime that basically ruined Kaneki's characterization. Instead of Kaneki being a human ghoul that choses to fight every once in a while without having to resort to become a full ghoul. The anime depicts him as some weepy pacifist shonen hero that won't fight at all since it'll be betraying his human side until he gets tortured at the end of season 1. So his random powerup feels cheap since he just all of a sudden gets super OP out of nowhere enough to take out Yamori while the manga Kaneki got fight training from Touka/Renji, kept reading books to learn fighting techniques which the anime basically skipped entirely, and was trying to get stronger from fighting back whenever he could. Skipping the whole book reference will also kinda kill the full impact of the Ayato fight when Kaneki is showing off his badass side and his textbook knowledge when he starts naming and counting off the bones he breaks as he's toying with Ayato.
The anime totally ruined the first Amon/Kaneki fight. In the anime, Kaneki basically didn't speak at all and just let himself get his ass beat until he got his super power up from biting him. So it was kinda like Kaneki only fought back in self defense or he shouldn't fight back since it'll be betraying his human side and then went into the whole leave Amon or I might kill you after he bit him. In the manga, Kaneki tried to reason with Amon at first but then he decided to fight back using the stuff he learned from Touka's fight training and then he bit him to get a little stronger in hopes he can control his ghoul desires. After that he immediately owns Amon and then tells him to leave since he doesn't want to eat a person. Which is way more powerful becuase Amon comes to the realization that Kaneki could've killed him whenever he wanted to and was holding back. Amon even says "It seems I was poking in a hungry lion" after his quinque breaks from Kaneki's attack. Which then puts the whole thought process into Amon's head that not all ghouls are bad and take an interest in Kaneki throughtout the rest of the series. In the anime, it basically turns into some Kaneki only bit him as a wounded dog type of defense since he didn't want to fight back at all. So yeah, it's a really big screw up on the anime's part. They totally messed up the whole original feeling of that battle.
Well whatever, it'll only be 60+ chapters for season 2 so they can't really screw it up anymore than they already have with this crappy season 1 adaptation. Would be great to see the fights animated since the animation is really good.

@Kizuchan:
On chapter 46. The only thing they've skipped so far is the Rize chapter and Touka training with Kaneki and Yomo, they moved the two arcs around, but for some reason I feel like it works better with those switched around. Maybe because of Kaneki's resolve at the end of the Hinami arc. I don't think the anime did it injustice. It might've cut some of the more unimportant stuff, and of course, censor things, but it works. Rearraging, but not really skipping. The themes are there, the character development is there. Nishiki and Touka best characters so far :) The plot, action and world-building is all relatively standard, but damn the themes and characters. Great stuff in those aspects overall. I hate the Shuu character, though.
They switched around the Hinami and Gourment arc which screwed up showing Kaneki's progression in his growing fight ability and the flow of the events. In the anime, Kaneki gets beating by Amon since he doesn't want to fight back and is easily defeated by the Scrapper in the Gourmet arc so Tsukiyama has to jump up to save him. In the manga, Kaneki is able to fight against Amon and defeats him after he bites him and gets some fighting experience from that. Then when he meets the Scrapper in the Gourmet arc, the scrapper is giving a suitcase and Kaneki is able to realize it's something similar to what Amon was using. He then is able to fight with the scrapper since he realizes the Scrapper isn't as good as a CCG investigator (Amon) but isn't able to damage his thick body. So Kaneki remembers the book he read in Tsukiyama's apartment and breaks his arm. Kaneki is about to beat the Scrapper then collapses from the paralyzing poison they put into his coffee before the fight. So Tsukiyama then jumps in to save Kaneki after he sees his one ghoul eye.
What's even more stupid is in the anime, Tsukiyama breaks Kaneki's arm and says "Was it like this?" in the church when they're trying to save Nishi's girlfriend. For anime only watchers, that is a reference that is completely out of context since the anime changed how the Scrapper fight went down so Tsukiyama shouldn't be making that reference at all.
