Highly entertaining
I will admit the sound is pretty bad, if you worked on that this would be alot better. The art work is perfect for what you are doing, its simple yet still good enoung so that you can tell there was some effort put into it. At first I thought you had just recorded the sound track from the movie and played it over animation...then it changed....LOL
Funny funny stuff. i wouldnt worry too much about people saying they hate this because Harry Potter is gay, the majority of them either have the books and wont admit it or cant read in the first place. I would concentrate on improving the sound for the next one and just go for it.
Tune the music down a bit, maybe put a kleenex over the mic while you are talking into it and that should help alot.
Good job.
