To imerse myself with the language I like to watch kids show in german. On YouTube I've found Total Genial, Totally Spies, H2O Plötzlich Meerjungfrau, Bibi und Tina, Code Lyoko... Kids/teens tv series have a story easy to follow from mostly the images. YouTube often have autosubtitle to go with it.
If I want to find a german title for a specific show I go on its wikipedia page and switch language to german.
