What would be the point of posting negative comments on your videos? If you plan on using them as a sort of "in your face" move and not move forward with the advice given, then you will look like the fool. If you plan on taking the advice and using it, then posting those comments will only show who led you down the right path. Either way, if you plan on using anyone's quotes you should probably get their permission to re-post them. Not doing so could be considered just as disrespectful as say, I don't know, the copyright infringement already pointed out to you.
Dizzi, can you show me where he's taken any of the advice given, cause I must have missed it. My opinion is that this video is newer than the others he has posted, so it wasn't filmed during the others. Look at the change in location and weather. It seems to be a park, and I'm almost positive I spotted other people when the camera was panning around. The weather seems nice so a live performance with spectators theoretically could have been pulled off. It's also been a month or so since he's posted a new video, so he's had plenty of time to change the music, the intro video, and the Lance Burton voice over. I understand where you're coming from Dizzi, but on this one I'll play opposite you and be the Devils Advocate.
