I only want to make one suggestion, here, and that is that the OP should take some time to examine exactly WHAT she wants to cut out of her life by ceasing to watch movies.
I say this because I believe that refraining from things simply for the sake of deprivation will ultimately lead to recidivism. You need to solidify IN YOUR OWN MIND why something is bad for you, and only then will the motivation to stay away from that thing really crystallize.
In other words, don’t stop watching movies because you read in the CR that it’s assur. Stop watching movies because you have identified something about them that you find detrimental to your growth, and because growth is your priority. If you believe that, the logic will fall into place.
