What is dis advantage of arena stage?

The main disadvantage of an arena stage is the limited sight lines for the audience. Because the stage is surrounded by the audience on all sides, there are certain angles from which the view of the stage may be obstructed. This can be especially problematic for audience members who are seated in the back rows or in the corners of the theater. Additionally, arena stages can be difficult to light and design effectively due to the unique shape and layout of the space.
