The writing is 'popcorn tier' I would say. Popcorn is tasty and enjoyable [...]
To me the problem of the main story isn't that it isn't good or that it's cheesy / shallow / just fun, the problem is it's broken, not working and obviously unfinished. Unenjoyable like popcorn with way too much salt. Luckily you've got enough tasty nachos on the side (origin quests and stories), but at the end of the game someone forces you to still eat all that popcorn.
The main story ending, or rather the lack of it, actively contradicts the choices and consequences principle BG3 is claiming to follow. And all the effort and success in bringing the characters to live (motion capture, cinematics, top notch actors) just to let them find themselves in a nonsensical story, what was that about? Spoil the finest organic corn cobs and the craft of highly skilled popcorn chefs just to sell more soda (that is, to promote the tadpole mechanics that is so much fun)?
It could be as easy as
- hey, you put way too much salt into that popcorn. - ok, sorry, I'll bring you some new till the end of the game.
Instead they're like
- I tastes so "powerful", exactly as we planned it to be, something's clearly wrong with your sense of flavor.
What ever the reason was for the mess of a main story, they seem to be unwilling to fix it at this point. At least that's the message they are sending with that ign interview. In retrospect the trust I put into the company by buying the game 3 years before release seems somewhat misplaced (which is ironic, because the very value the stories in the game are created around is the question of who do you trust.)
