I regularly use slide, neg and B&W neg film that is over 5 or more years old.
Mostly they are ok.
In my experience, chrome film if properly stored is good for up to 4 years with no ill effect. Over that, you have to run a couple of sheets or rolls to see.
B&W neg is a whole different game. I have used some that is over 25 years old and its great. It have a slight base fog but that adds to the look. Over 25 years and it a crap shoot. I have some nitrate based sheet film from the 40's. I can barely get an image but it looks cool.
2005 film are babies. I would have no problem using them. But i would stress that you need to run some and see.
