I think it has a soulful feel, an earthy, handsome underused name. I think, having seen
Silas and
Ezra become popular recently, I think it would be incredibly usable.
I haven't seen the show the other comments have mentioned, but I know it is the spinoff to Breaking Bad. I also know the character
Saul Berenson from Homeland comes to mind. Sometimes this sort of familiarity is helpful though in making a name seem more comfortable for people.
I generally like this name.
