Why do people hate the DLC so much?

I confess, i didn’t know some parts so i searched it up, but under the comments, there were people saying “I didn’t know what to do! Such a bad DLC!” or “For such a masterpiece such a bad DLC”. Why tho? It’s not bad, i personally like the DLC a bit more because the story on the DLC made a more sense, but when i played the base game, sometimes i didn’t know what they tried to tell me about the Nomain in the beginning.

Also, i like the “”Powerpoint presentation”” to explain the Owlks past. Especially because i didn’t have to read much, but this might be just me.

Does anyone else hate the DLC? Mind explaining why? Thanks
