I wrote a longer review of this episode, but for some reason it wasn't published?
Visually, this is the best CGI I've ever seen in an animated series. Mappa have raised the bar higher than ever in that regard with this episode. Just wow!
As for the episode itself, for every second I was on the edge of my seat, eyes agape, verbally letting a few "holy ****s" throughout.
I've been with AoT since its release in 2013, eagerly awaiting each episode, and of course there are certain standout and viscerally memorable moments throughout the entire series, such as Armin plugging the wall with the boulder in Season 1, the Female Titan pursuit and confrontations, and especially Episode 17 of Season 3, which also is the only other AoT episode to score a perfect 10 in IMDb thus far, which shares a certain common blonde-haired denominator with this new episode, arguably the most relatably human character of the entire show.
Soundtrack and sound-design wise, this episode is phenomenal. Man the entire episode is just stellar and, dare I day, perfect.
Seven episodes down, nine to go... [at least?]. I don't know whether to be hyped or to cry that it's ending soon... but either way, if the show keeps up its integrity and quality that its displayed in this episode, then AoT will go down in history of one the absolute greats.
