i like the story
people who are not sure if this is based on a a true story, this kind of love story happens all around the world. the ending was good but kind of unrealistic in some ways though.
if your wondering about the weird ending, i got reminded about the quote at the end of episode #1, i would type it but i dont want to have spoilers, so i guess have a think.
the southpark style was alright, it could have been a little better, i was expecting to see better graphics as the episodes went on, but i guess you didnt try to improve and keep the same style, or you just did it all at once and seperated it for suspense.
the voice acting/quality/script should have been better, especially when he met up with her, but i can see you didnt want to stretch the movie too long.
foreshadowing was good, but it was not fully clear at the end what exactly were the reasons, it all came to sudden, unless i missed something before.
something i would change for watching the series a second time would be to change the emotion of the endgirls face in episode1 to sad not happy.
i wish i could make an animation which gives the viewer strong emotions, maybe sometime in the future :P
good job.
