I had the same reaction to it, but ended up buying it after looking into some gameplay. I’m glad I did because there’s a really enjoyable game outside of the “sex appeal.” Combat is good and fun, there’s an interesting story there too. My only major complaint is that about 2/3 or 3/4 through the game it turns into a boss rush, and almost feels like the devs ran out of time or budget so cut some story.
As for the community, it’s easy to get around that by just not taking part. I’ve avoided it for the same reasons you’re not wanting to play. It’s a shame there too because I imagine there’s well meaning people who truly love what the game has to offer outside of fan service, and would love to discuss lore, etc.
Yeah waiting for a sale is a good idea if you're uncertain. I bought it full price on PS5 and don't regret it because I felt got my money worth - spent enough time with it for multiple play throughs, platinum trophy, etc
