Can't really tell. Some people will shoot film because they did that before. Some do it out of curiosity. Others will completely hate the idea of waiting at least an hour before you see your pictures. That is if you have a film lab that's that busy. Most of the time, the waiting time is more than a week. Some take months even. You'll never know unless you ask and that spoils the surprise.
Given that, there is also the risk of running into a used camera that doesn't work. When buying cameras at this level, it is highly recommended that you test the item personally first before handing over your hard-earned cash. If you're doing this deal online, forget it. If you don't know what to do with a fully manual film camera, get her something else instead.
Search "The 5 Love Languages". Figure out what's hers (and what's yours too while you're at it). Take the test. There are lots, free, online. If you know how she wants you to express your love to her, you'll know exactly where to spend your cash. Better yet, you might not even need to spend at all! ;)
