It was his physical issues. Seeing that he was practically just bone and skin brought them up.

It's not that I couldn't finish watching it, but I just didn't see the point.

The worst are slasher films, though. I've sat through a few Saw films, but parts of them made me physically cringe because of how I "felt" what was happening.

I get the same way when something horridly embarrassing is happening, though. You'll have those films that have a few moments of someone pretty much just disastrously failing at all things. They're supposed to be funny and more slapstick than anything else typically. For some reason, I cringe at them as they go on and tend to get a weird feeling that comes over me that makes me want to change the channel. There was even an I Love Lucy episode I watched once that made me feel this way.

It's not something I can easily explain other than having a heightened empathy towards such situations increased by a very overactive imagination. I'm one of those guys that can easily bring to mind a visual scene and make myself cry like a little baby from it. I'm a crap-tastic actor, but I can cry on demand because of it.
