Very bad
Where to start...
The graphics/drawing/animation was terrible. Very shaky and none of the lines matched up.
The sound was terrible! The voice acting was no where near the actual voices, and oh god how it tried. There were multiple long gaps with no sound but white noise. Minus 3089 points for that.
And why try to write a whole new Family Guy episode on your own? Leave that to the actual animators.
I hope this gets a Grade-A Blam.
