So, episode 9 does have 6m20s of new footage. More than I thought they could cram in there, to be honest.
They did the intro credits during Griffith's hallucinatory flashback to save time. Some small cuts were also made to quicken the transitions between scenes. Casca's face was redone in a few scenes during the Silat fight and her talk with Guts. Guts' face was redone in a scene too. This is just the usual improvements they do, but it's notable that these don't really look better than the original ones IMHO.
It seems like they added a few seconds of footage during the love scene at 16:40, where Guts is shown opening Casca's legs. Maybe that was a pre-existing Blu-ray only "unrated" scene though, I'm not sure. I'm not going to bother myself comparing between versions. In that same vein, parts of the scene were censored during the TV broadcast, but the Crunchyroll version is untouched.
They also lengthened the scene by a few seconds at 17:25, but Guts is still very much made to be a quick shot with how it's edited. Embarrassing.
At 17:30, new footage begins. It reuses some of the material from Guts' previous flashback, but it's mostly new stuff, and the first picture makes it very clear he was raped as a kid, unlike the existing dream-like sequence. However, since it's inserted at the wrong time in the sequence of events (compared to how it happens in the manga), the way he ends up strangling Casca feels like a continuity error, it's a bit nonsensical.
On a positive note, the dialogue is mostly faithful.
Visually, the 2D is passable in close-ups, but looks embarrassingly amateurish in wide shots. They also give Guts some ridiculous eye movements when he tells Casca about Gambino (eyes moving independently from one another), which just looks stupid. Frankly, it's kind of an insult to the character and to the gravity of what's depicted in the scene.
For
@Imperivm97, the new music starts at 22:25. I would describe it as unmemorable. The end credits start at 23:30 and are overlaid on the scene while it keeps playing. The new footage ends at 23:50. The music ends at 24:00. The episode runs overtime at 25:04 and ends abruptly as Guts and Casca lie on the blanket, right before the transition to the Skull Knight scene. Makes me wish they'd salvage it in episode 10 by not having SK appear to Guts while he's naked with Casca right next to him but inexplicably impossible to wake. Sadly, that'd be be too much work.
I have to say, it is truly painful to watch this mangled version of the story. I appreciate the Memorial Edition's efforts to right some of the wrongs of the movie trilogy, but unfortunately it's just not enough.
