I actually watched episode 1 again because a guy told me how great he thought the first episode was..... (He gave it a 10/10 wtf)

I was surprised and started rewatching...and honestly, now after watching it twice I like it even less, lol.
The worldbuilding is horrible.

Guy in suit (no matter who that character is) drops information about how everything works, with images flying by. The lowest, easiest, and least interesting way to do worldbuilding.
People saying shit like "Oh no, our "RANKS" are too low" (oh okay, that kinda felt forced though..)
The captain mentioning "our guns don't work anyway..." (hmm okay I see)

Then after all that, the freaking association dude explains EVERYTHING for the dumb people, literally everything we've seen with actual images first, even if they weren't all that great.
It's like they went for the "show, don't tell" approach and then said "ah naw, we really have to actually say it out loud, or they'll miss it".

I honestly think a 5/10 for that first episode would be a fair judgement. The animation was real jank from time to time too (the scene in which MC hid behind a stone and the group was fighting against werewolves and goblins)

If they had started with the Gate mission, like the manwha did, I honestly believe it would've been a better episode. The attempted worldbuilding and explaining made everything worse in my book. Frontloading everything instead of letting us explore it is just a worse way of doing this imho.
