Helllo , It's not bad or Good that much . It is Backlink means Links pointing to your site which is positive indication . As per the General rule , we should try to get quality in links for the site as many we can . The page which is linking us should have less outgoing link, Quality content , Good PR and overall Good Traffic . Anyway this is a good indication to get a one way link evenif it is PR 0 .Do not forget that PR 0 is also a Google rank that mean the page is indexed and in Google's Data base . Have a nice day
