You fell in love with a game and it's characters, sunk hundreds, maybe even thousands of hours into it. It became a comforting, immensely satisfying part of your daily life. Then you heard a sequel was coming and got really hyped but when it came out it was utter rubbish...
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.
