That was one of the humorous criticisms I saw - why do some ghosts have the clothes they died in and others get to wear formal wear? I'm assuming Melinda's dead brother-in-law didn't fall off the roof wearing a tuxedo, so he got dressed up for their wedding? Also, every time she goes to hospital or nursing home there are ghosts everywhere. How does she decide which ones to help? Why doesn't she go back to the hospital to take care of all those lost souls?
