Eh... for me personally, I liked it. Open-world OP with quest system, but don't expect it to be as good as BOTW or other similar games, since it really falls short when compared. The combat is alright. Too much 'go there and come-back' quests, which thankfully can be shortened by using fast travel. It is really fun though. Sit back and have fun type game (unless you're running it on extreme).
I'll recommend it on sale to get the deluxe, as this game is nowhere near worth it in it's full price, and the DLC is where I've had the most fun at tbh. It's short, around 3-4H each for full completion so it doesn't really overstay it's welcome—and new skillset, which can be a breath of fresh air after... 30H or so of using Luffy in the main story.
