All the time...although not Polaroid. Polaroid cameras were always crap, although Fuji FP100c shot in a proper camera could be amazing.
I regularly use a Nikon F2 and a Nikon F6. I have a whole pile of other cameras, including nearly every film Nikon made, but these are the two I come back to most. My F2sb has an amazing meter and gives full metering support with nearly every Nikon manual focus lens ever made. For times where I want to use something the F2sb doesn't work with, I have an F2AS that works with every AI-compatible lens. The F6 works, including full matrix metering and full feature support, with every AI, AI-s, AI-P, AF, AF-D, AF-I, AF-S, G, and VR lens made. It can't operate the aperture on E lenses, or focus with AF-s lenses. Since I don't have any of those, though, that means I can stick it in the bag with my D810 or other DSLRs and use all the same great modern lenses(aside from the current gen f/2.8 zooms, which outside the 14-24mm f/2.8 are all E aperture).
Tri-X, FP4+ and HP5+ are all easy to get and I will never let someone else develop my B&W. Provia 100f, Velvia 50 and 100, and Ektachrome E100 are all easy to get, and Dwayne's Photo in Kansas does a great job processing roll film. If you want negative film, the modern Kodak products, including Ektar 100 and the Portra line, are excellent.
For serious work, though, forget 35mm. My Hasselblad and Pentax 67 are the tools of choice. I dabble in 4x5 a little bit and have a Calumet monorail(I sold my Speed Graphic as I found it too limiting and not that much easier to carry around than the Calumet). I've done E6 sheet film at home, but it's a royal pain and I need to dedicate an entire day to doing nothing but processing since the chemistry is good for about 24 hours once mixed(and that might be stretching it). 4x5 B&W is in a way even easier than roll film-I have a processing tank whose name I can't remember, but it was a kickstarter project that came to fruition a few years ago, and is a nice daylight tank that holds 4 sheets and 16 oz. of chemistry. 4 sheets of 4x5 are about the same surface area as a roll of 120 and a little less than 35mm-36, so that's good for something like D76 1:1. The old hard rubber tanks with hangers are easier as long as you have a real darkroom.
I love printing in the darkroom too, even though I'm not great at it. I've given a few 16x20s(printed from 6x6 Plus-X, which I have a big stash of, using the Hasselblad) I was quite proud of as gifts, and given that my darkroom was set up to handle 11x14 at the largest, getting that developed properly and then washed(I used good fiberbased paper) was fun. I did a bunch of 6x6 and 6x7 contacts on the beautiful discontinued Kodak Azo, and I always loved those but I only have grades 2 and 3 so I almost had to shoot with the intent to print on it(I normally end up at about a grade 1 or even .5 on multigrade paper).
Film is fun.
