Just like anything that provides you with an extreme experience, like high doses of sugar, caffeine, cocaine, movies are addictive and can warp your sense of reality by tricking your brain into believing that the emotions you feel while watching them are real. You're having movie magic withdrawal, and it sucks, truly it does; however there are some magical experiences that can be ten times better than movie magic, most of them being on the astral plane - which may sound like a cop-out but have you ever had a hyperrealistic dream that was better than a movie? I'd recommend getting good at it, but seriously speaking it takes a lot of work and you do have to earn it.
That in itself is a good thing though - in real life you have to work to have nice things and that's just it, and the quicker you stop fighting it (pointless) and start working (satisfying) the quicker you can start having fun again.
Also, if you really think about it, movie magic would be disastrous if it suddenly broke into this reality, as it is.
Imagine Trump or Hillary being able to cast the Cruciatus curse.
