I wish they made the Music Meister more like Neil's version rather than Mr. Mxy's cousin. The singing cast members well, especially Melissa, but the singing often felt out of place. John Barrowman's inclusion also was a bit shoehorned given Malcolm had no personal connection with Barry.

I wouldn't have scored it that high, but good review.
