You might want to be a bit careful with those.

Starting from around episode 20 they made some big changes in the anime compared to the Manga and some smaller ones to even before.

In the manga they first go to Zagan and then upon exiting the dungeon are attacked by the Dark Metal Vessel users, but in the anime, the DMV users attack Sindaria WHILE Alibaba & Co are in Zagan and the whole thing with Alibaba almost falling into depravity was build up quite a bit more. In the manga it only really plays out inside Ali's head.

Untimately it doesn't affect the overall direction of the story, but people still have been going nuts over it in the past.

While I'm not at all fond of the changes, I don't see why people would get THAT upset over them though, since as I said the "landmarks" if you will of the story are still kept and it's mostly shuffling around locations and timing.
