Pics were (all but the last one) very good quality, the progress saving was handy i guess. The background for the final 8 questions is a good one, by far better than the plain colours but you need to adjust the text colour (even a different shade would make it more legible)
All in all, nothing to flash or great, but as far as dodgy online quizes about tv shows i guess it'll fly...
I give it 4/10 - 2/5... sorry dude, south park IS great, it's unfortunate that your quiz wasn't...
