I can tell why people love it
To start with the positive, i really liked the way you drew and animated the flash. It is a step up compared to paladin and your style starts to feel look pretty professional. The way the strokes were drawn and the good tweening even reminded me of Xombie and that is a big compliment. A few parts were still a bit awkward though, with the arguing silhouettes of the parents looking more like stick figures rather than real proportionate people, or the tiny cars next to the sidewalk.
Since so many people love this flash for it's serious message and content, i thought i'd write a review for it from a slightly other perspective. To be honest, i didn't think it was that special or profound, especially since there are a huge number of cliche scenes and shallow characters that ask a bit too explicit for the viewer's pity. Arguing parents, loner boy with talent, Rise/Fall and a simple moral is not something we haven't seen a lot before. The thing that annoyed me the most though is how there is never really any development and how each scene just passes to reveal the disney ending.
Like the 9/11 flash 'i miss you daddy' that everyone loves, it is a bit too melodramatic and in your face. In my experience, younger people are easily affected by this type of imagery, while adults like to form their own judgement about what's happening and who deserves pity and who doesn't. A good dramatic short contains characters that have weaknesses as well as strengths and that don't drown in self pity, but gradually conquer the viewers hearts while the movie passes. A good recent example is the brilliant movie Babel, with awesome deep characters that we can both love and hate at the same time.
Like i said, this is my take on the flash and the drama genre in general. It is by no means more true or false than the ones of the people who love it, but perhaps you can experiment/do something with it in one of your future films.
