The first and 2nd episodes seem to provide a false hope that the anime focuses on the action genre. The first floor boss covered elements of tactical raids and was quite an in depth fight. The general emphasis on the flow of an MMO game, it certainly seems to set a path towards an action show, which in the west is the most appreciated type of anime. Action-oriented animes tend to be well received and the most popular outside of Japan.

After the first couple episodes, fights are implied and don't really contain much action. It seems to skip ahead floors, and fights are not as rich or significant as they were at the start. The anime switches to be more plot driven. The plot becomes implied and requires you to think, with many ongoing mysteries. Elements of romance are frequently introduced, which many were not looking for in a show that is supposed to capture the feeling of a MMORPG.

Because of the reduced emphasis on action and increased effort put into other aspects of the show such as romance or mysteries, it upset many people as it was not what they expected.
