It's not a negative comment; it's feedback.
Want to know why I'm not patting you on the back? The hard truth is that I feel that everyone who participated spent a lot of time in this, to have a harlem shake video, but the end result is entirely not what it should be. I understand you wanted to make it longer, but it was moot - you just have 1 min of nonsense to the beat of the song, instead of the actual Harlem Shake and why it actually got famous.
Just re-do the editing and make an actual one!
