I find them very interesting . It's healthy to have an interest in the various issues that affect different individuals I think.
Especially with something like ED's as we as a weight conscious group are more closely exposed to it and there's a thin line/ grey area that can be easily crossed if we're not careful or push ourselves too hard.
Some people view ED movies as extremely harmful rather than educational as they trigger some people. But usually you have to have a mental inkling as in anorexic thoughts, tendencies and a tension, emotional stress tied to food etc.
However if you're in a good place but are very careful /worried about weight gain and / or weightloss then they can be very helpful coz it gives you guidelines.
Sooo after that probably unnecessary lecture/ rant. I like them. Not 'like' but I find them very interesting and educational.
