How do you get kids to stop watching movies?
Give them a test on it...
In our schools there are tests and marks which makes kids dislike/hate/despise the subjects studied. Do you know anybody who studies his old high school and college textbooks in his free time?? After we are done - we are done. Since Gemara is a "subject" - kids don't fall in love with it.
So sad.
[An idea I heard and agree with].
