Pretty horrifically bad. The plot is nonsensical and trying too hard. They focus more on aesthetic than content. The artsy-fartsy mind palace scenes are ridiculous and many scenes the lighting was so poor you couldn't see anything. Major plot points just are not corroborated by flashback scenes or what they reference. They tried to ride the knives out train but failed in the most important aspect - the story. Watched it fully to give it a chance but it took effort to even see through watching those last few episodes. I love a whodunit but this is just a bucket if ridiculousness.
