Forgive me if this seems a rehash of the above.
Most " accomplished" Photographers have used film to hone thier craft. It does make you think before you shoot ( as the cost of film/ D&P) can mount.
Added to that is the wait to see whether your shot was what you thought it was and (as was stated earlier) not all processing labs have tight Quality controls and you can be at thier mercy even when youve done all the right things
I do still have a Film SLR (: have had 5 to date) but havent used it now for 18 months.
Digital "absolute quality" is still behind film at the same price point but the gap is narrowing
If you are just starting off , may I suggest you get an affordable second hand ( "lovingly pre-used" )

or new(ish) ex-demo DSLR.
You can still learn valuable photography skills ( and new ones : Post processing) which will be more helpful unless you wish to go "Pro" and end up still using film.
If you dont see yourself using film now or in the near future you lose nothing by "learning" with digital.
I suspect that some of the "masters of the art" who no doubt have great skills have had to unlearn some in this digital era and learn a few newer things. Seeing as digital is "New" who knows if they would have gone straight to digital if it had been as readily available in thier day as it is now
No matter how much we extal the virtues of film, many film companies (including KodaK) have bowed to market forces and have either folded up, downgraded thier film divisions to digital or merged with other firms to keep going so there is no gettting away from digital.
Im sure someone here will agree that you dont have to pay for film, D&P, and the wait for the D&P to improve yourself.
However as you have access to your Dads camera, you can take some pics with it , "borrow" say a Canon 300D take identical pictures and do a mental comparison.
