I don’t play D&D - in fact I don’t play any TTRPG anymore (imagine having friends) - but I’ve heard a lot of criticism about WOTC’s products, yes. A lion’s share of it is about how unhelpful the official adventures are for DMs, but I’ve also heard the writing criticised from time to time.

I’ve heard good things about Waterdeep: Dragon Heist and the Curse of Strahd remake though.
