you will not hear me argue for how "AWESOME" and "CREATIVE" the second one is, but as a viewer .. All i see is the cartoon, so when deciding which is better, the soundtrack has a lot to do with my decision.
I respect the original a lot more ... but would I be lying is I didn't say that adding the "Mad World" music didn't help me enjoy it more? yes.
Meh, that song in my opinion is good, but very overplayed and overused.
I've seen a lot of videos put up to it, and I adore the original soundtrack, which his friend composed and recorded.
