Film has one major advantage over Digital, Latitude. Digital has a latitude of about 5 stops, similar to slide but colour negative film has a latitude of 7 stops. B+W film has a latitude of 9 stops.
Also the use of film makes you slow down and think about the art of picture taking where as with Digital you can blast away at a subject and select the least worst image
Also as Leon mentioned, negatives last a long time. How long will the digital images last?
But, digital is convenient.
