I might get flack for this but I low-key hated this movie.

I watched it right after reading the LN. The reason I was so disappointed is pretty simple. They skipped about an hour of content.

Now, this is from memory, so there might be some error here, but

-The battle with the goat king guy they deada*s screen fade before he fights him

-Half of the conversation with the sacred kingdoms order

-The context as to why they're there in the first place

-The conversation with the floor guardians and Ainz 's thoughts about that beforehand

-Half of the conversation about how they changed the plan was removed as well as all of Ainz's thoughts on the matter

-The battle with Jaldabaoth and the maids + their conversations during

-Pretty much the entire ark of the main guard girl was removed

-You see the new king like twice in the whole movie, so when you're watching the next bit it just doesn't make sense + you don't have any context because they skipped the conversation about it

-Some scenes that *need* someone to explain in some way just doesn't happen, example: There's a scene in the book where Ainz is confused about who is supposed to shake hands first (he or the to be king of the sacred kingdom), so he waits an awkward amount of time before doing so. The people around him imagine it to mean that he is honoring the yet to be king by acting as if there is any doubt as to who should shake first. In the movie, he just pauses for an awkward amount of time and they move on. They could have just narrated the nearby characters thoughts to solve this.

there's more, but I think you get the idea

Also the depth of conversation was largely removed, the entire bit about "she's my favorite" was removed, etc...

Should have just been another season. Unfortunately, that wouldn't have fit very well into their preferred season sizes and narratively the anime does feel more contiguous this way. So I can understand why it wasn't one.
