" I shoot film because it requires me to slow down and think about each shot; I can't fallback on "guess and check" for exposure or composition."
Funny, I shoot film on my Minolta X700 (for over 25 years) because I DON'T have to slow down. What I see in my viewfinder is exactly what I'm going to see on film. The joys of real SLR versus Digital SLR. Your camera screen is not reliable for color reproduction - raw optics are.
Film doesn't necessarily match the color response of the eye any more than digital sensors do. Fujifilm's Velvia film was renowned for extreme saturation, not accurate color reproduction. And optical viewfinders don't take into account exposure length either, so they won't give an accurate view of long exposure shots.
If you shoot raw you can always tweak the color balance in post-production anyway.
"And optical viewfinders don't take into account exposure length either"
The Minolta X700 does do that via a secondary faux-shutter mechanism and a light sensor. If you actually bothered to have a battery installed (which dies after about 8 shots,) the tiny auto-exposure sensor inside would take over and the faux secondary shutter would move out of the way.
The shutter in an X700 is timed electronically and won't work without battery power, a common fault occurs when one tiny capacitor in the timing mechanism fails, preventing the shutter from releasing.
I have no idea what the faux shutter is because the camera had a fairly conventional horizontal fabric shutter. The actual innovatation is with the closed-loop AE mode where the camera will account for a faulty aperture or more importantly, non-TTL flash by measuring light reflected off the film in real time.
Most DSLRs I know of use the same mirror and pentaprism arrangement as a traditional SLR. Yes, they often do have an additional digital screen, but I only use that when I'm trying to find a specific shot on the card.
Yes, and they all pretty much suck. Auto-focusing optics that can't handle a scene because the sensor thinks there's changes in focus from even the slightest noise, poor color reproduction on built-in screens, sensors sensitive to even the slightest jitter of the internal components, shutter roll effects in video, and more. Almost every one of these problems is not happening in an analog SLR camera.
1) Autofocus can be turned off if you don't like it.
2) There's no (electronic) "screen" involved when you're looking through the viewfinder of a good digital SLR. It works exactly the same way as the viewfinder on film SLR. Exactly.
3) The same is true with respect to "sensors". Every DSLR I've used lets you shoot in full manual mode. No sensors involved.
4) I'm not sure what "video" has to do with it, since you can't take video on a (still) film SLR anyway.
"Autofocus can be turned off if you don't like it."
Excepting some lenses themselves have one built-in that you cannot disable.
"There's no (electronic) "screen" involved when you're looking through the viewfinder of a good digital SLR"
Tell that to my Sony SLT which has... wait for it... an electronic viewfinder. Oh, and many people find that focusing manually using an EVF is easier than with an OVF because the EVF allows you to magnify an area to clearly see when the subject snaps into sharp focus (assuming no cruddy interpolation,) which is why DSLRs are coming with an electronic viewfinder.
"Every DSLR I've used lets you shoot in full manual mode. No sensors involved."
Is that including the sensor which is required to take the picture?
"I'm not sure what "video" has to do with it, since you can't take video on a (still) film SLR anyway."
What do you think is inside a Super-8 camera (which has still film modes?) The exact operating mechanisms, down to the split prism (well, some used a half-mirrored optic) that you would find in a typical SLR. Oh, and then there's this thing called rapid continuous shot (battery assisted, of course) where you can shoot up to 30 shots per second with my old camera, which means... wait for it... VIDEO SPEED PHOTOGRAPHY.
