“If time didn’t have a direction, it seems to me that would make time into just another spatial dimension, and if all we’ve got are spatial dimensions, then it seems to me nothing’s happening in the universe.”

The directionality of time is a characteristic that is different than spatial dimensions but it is not the defining characteristic. Simply making time non-directional does not transmute it into a spatial dimension. The thing that differentiates time from the spatial dimensions is that time is a temporal dimension not a spatial dimension, irrespective of its directionality.
