digital guy here, in the process of buying a film SLR for the nostalgia of it. question is, how long is film good for? i just had a daughter and while extatic over that it puts a damper on my expendature plans. i have about 20-25 rolls of film that i'd rather not get rid of sitting in a tin box in the closet. will it ever go bad? how long can i hold on to it if i keep the rolls in the dark?

Film can definetly go bad over time. I keep all my film inside the fridge as it prolongs shelf life by more than double. Moisture from the fridge isn't usually a problem as I myself store it on the egg rack and it has had no problems of moisture damage.
Usually Film will be at its best during the first month or two after purchase if it is sitting out. After like a year or two it will either get really really grainy, or get color shifts so its best to use them as soon as possible to get the most out of quality.

As has been said, film comes listed with an expiration date, however if kept cool the film can last amazingly long. I keep my film inside the plastic container to keep condensation out then I put my film in the freezer.
As you know, Emulsion is a chemical mixture, and like all chemical mixtures, there is a constant chemical reaction taking place, albeit a very slow one; that is the Silver Nitrite breaking down to Silver Nitrate (or something along those lines). Basic chemistry class tells us that heat speeds up chemical reactions, and by removing heat, chemical reactions slow down.
