It's funny, because I recently went back to film. Have hardly picked up my DSLR in about 3 months.
Percentage-wise, my keeper rate with film is close to the 95-99% rate (as long as I develop the roll correctly), whereas it's the reverse when using digital. I find each film shot is much more planned and thought out, everything is double-checked (exposure where I want it, composition, etc.) before I hit the shutter. When I'm using digital, I'm a lot sloppier, having the mindset of "I'll just shoot a couple more" or "I'll fix that in post" and the like.
I was just playing around with a new-to-me Nikkor 60mm Macro earlier (I recently picked up a Nikon F4s, so I've been using that for film). I shot a total of 17 shots in the course of an hour. Nothing special, just some backyard macro stuff. When I get a new Canon lens, I burn through 100+ shots in the same timeframe. Of those, maybe 10% would be considered keepers (although subject matter usually makes it 0% as I'm just testing and playing). Of the 17, I'm expecting 15 or 16 keepers (I know I screwed up one shot).
So, no, you're not alone. If you want to improve your keeper rate, the best suggestion I have is to slow down, and think the shot through as if you only had one chance at it. Your keeper rate should go up exponentially.
