Unfortunately I didn't really get into this series till near the end of its life. When I first saw it, I was annoyed at all the pop-ups. They detracted from the video. Then when I actually took the time to watch it, I realized that was the whole point.
I've always been a fan of riffing, I saw this was just a new way to do it. All the info was tidbits about the video, the song, or the band you might not otherwise know. Much of it was funny info, and some of the comments were very sarcastic and witty.
I admit it got somewhat repetitive, but I still enjoyed it. TV needs something like this back on the air.
