You see, I wouldn't consider this "unfair". Unfair voters are people who see that its a lock movie, auto blam and leave thoughtless reviews like "you sux teh cok" and such. You have a reason for not liking it, and I respect that. Thanks for your honesty!
Now to your points...
1) The sound quality is low because the higher the quality, the higher the filesize. Im sure you don't want to wait for 3 MBs... But I can if there are enough complaints.
2) The scenes are short because the songs are short. Simple.
3) You have to click the center of the play all button. Trust me, it works.
All and all, it seems you have a short attention span, but an honest heart.
