Can someone help me with this lighting?

So I’m just trying to make a simple interior environment, and for some reason in certain rooms, the shadows cast by lights look really ugly and inconsistent.

Like with this picture here, you can see that one wall has shadows like I want it too, and one wall seems to not have any shadows on them, and it just looks ugly. If anyone would be able to offer some advice, I’d be more than grateful. Thx
