The Amazon page makes it clear that this is actually season 4 instead of the 3 it's labeled as, which is annoying, but whatever. The major issue is the music.
As is common for DVDs of shows from this era, getting the rights to the music they included involves a renegotiation and some new payments. Clearly, the powers-that-be decided it wasn't worth it, because they replaced most of the music, INCLUDING THE THEME SONG, with poorly chosen and not particularly good replacements that don't work with the (admittedly already weak) dramatic moments. It's extremely distracting, and makes a weak show even harder to watch- I got this for my boyfriend because he has fond memories of the show and a bunch of VHS tapes that I'd like to get rid of, and he couldn't make it through an episode.
If you actually want to watch this, buy the German print, they love Hasslehoff enough that they've paid for the original music- they even have the American dialog as an option.
