Yes, I agree with learning English through movie. Find something you like, movie or Youtube topics you like. Maybe about make up, celebrity or sport. Watch it with English subtitle so you can catch the words, after that watch it in your native subtitle you you know the meaning. You should find some popular slang or urban words, then you could use it to express your feeling, like updating status using English. Make English caption for your instagram.
Actually, commenting in this forum is also a form of practice
