Tower of God starts out pretty simple, slowly expanding and dropping little bits of lore, character development, and world-building as it goes. It's a more traditional approach that imitates shows like Naruto, One Piece or Hunter X Hunter, and one that maybe isn't always as appealing in modern fast paced (impatient...) culture. The difference with stories like this though is that the payoffs tend to be greater, the world more immersive, and the story threads complex and intriguing.
The artstyle is hit or miss it seems (and I mean REALLY hit or miss. Most either absolutely love it or flat out despise it). I love it: it feels old school and almost hand-drawn (imitating the style of the webcomic). Strangely, when I saw stills of the series it didn't look very appealing, but somehow seeing it in motion is a whole different story.
Then there's the music. The OST is made by Kevin Penkin whose done some other famous series and it's on a level of quality I rarely see in anime. The OP is done by kpop band Stray Kids. Not having really listened to kpop before, I can say that I absolutely LOVE the OP. The visuals are a little lackluster to be fair, but the song is incredible.
Now I will say this is the sort of series you can get lost in if you're not paying attention. Pacing wise so far it's felt pretty good (although episode 6 felt pretty fast in comparison to the first 5 not that's necessarily bad). I know they're fitting in a lot from the original webcomic into a short period of time but so far most of the time it feels like it avoids some of the pitfalls the longer stretched out shonen anime of the past tend to fall into.
Overall the series thus far has been pretty spectacular and, to be honest, a refreshing breath of fresh air. Anime as of late has really started to feel a bit stagnant, with the same sort of stories being made over and over. It is true that not everything here is completely original, and it's not without a fee flaws, but I believe it really manages to capture the immersion and massiveness of a different world (or universe) and do it well. I'd say definitely give it a try and if you enjoy it, consider catching up to the webcomic afterward (on webtoon). That's what ended up happening for me and I can tell you I don't regret it.
One final note: the characters are pretty great in this series, although the main character Bam does appear a bit overly simple at first. There's good reason for that but I've noticed it turns some viewers off the show a bit. If there's one thing I can say about Bam after having read ahead (not a spoiler) it's that there's a significant amount of effort put into his development as a character, far more than many series I've seen, but it doesn't happen over night. It builds up over time and in pretty surprising ways, but you will have to stick through it to get there.
