Journey was huge in the 80's. And it wasn't because of their videos. I think we all tolerated the videos just to hear the songs.
Set in a shipping yard (for no apparent reason), "Separate Ways" features really bad air guitar, air drumming and air keyboarding (is that even a thing?). There's the obligatory good looking female. Then at the end, it appears all to have been a dream.
If this video were ironic, it might make sense. But given the timeline and the advent of MTV, I think it's just bad. Judge for yourself.
