Most of the videos also contain subtitles, which defeats the purpose of the exercises (you can disable the video manually though). Another issue is that some of the words are segmented very unnaturally (e.g. [み][ません]), so it's unclear how you're expected to fill them in.
In the end if what you really want is "real-world content", then you just need to go out there and find them yourselves - they're everywhere.
