well, this was sad, and nicely depicted, as it showed us a devastated, broken sonic, who barely clung to life, and whose time was soon coming to an end...
(its similar to the actual status of the character in the videogame franchise: the character's popular and he's nicely designed, but his games have long-lost their artistic flare/the ''fun'' element a long time ago, and nowadays, only silly/random/empty games with sonic get created, with the result of lower sales for (new) sonic games, and the eventual ''death'' of the character...
and
even if sonic's existence will get prolonged+supported by various nostalgia fans/random gamers/sonic-lovers(both in a good/bad way)...
soon, one day his presence will end, due to the developer's lack of commitment/originality, which damage the whole v-game industry, in many ways.
(a repetition, that is also seen in various super-mario/luigi/zelda titles, to a lesser extend).
NOW! about the movie:
the start/setting was excellent, the hospital was drawn nicely, and i liked that the background had a dark, gloomy sky, showing the general melancholy of the whole setting...
also, showing mario appearing through a green pipe in the hospital's front yard, was another good detail! bravo!
the nurses/hospital room/sonic/sonic's friends/mario AKA=the whole characters of the movie were nicely drawn, they had good face expressions, their movements+actions were nicely animated, the whole scene was executed perfectly, with NO need for dialogue whatsoever, (which is a difficult thing to achieve in a movie, and thats good...), and a nice sequence of events, which lead to the character's tragic demise:
sega created (yet again) one more (unoriginal) sonic game, and it turns out that THIS was the last straw that killed sonic, making him to fail and to die, which resulted in mario preparing a ''+1-UP'' (extra life/revival) mushroom, (in order to save sonic), but alas, shadow told to mario that ''it was too late''(and that people were beating a dead horse, in this case, a broken idol...).
so, sonic died, and his life-ring fell down, and crumbled in pieces... (this was also one of the best scenes in the whole movie, very nicely animated, with good FPS speed, and good details, it was by far one of the best+most memorable scenes of the movie... very sad and dramatic...)
also the character's expressions with them seeing sonic's end were spot-on, from the obsessive girlfriend amy, to the devastated friend/protege of sonic, tails, to the calm+reserved shadow, who grieved his acquaintances death in a more distant, ballanced way... with some sadness, yes, but without any obvious signs of strong emotions...
thats shadow for you!
all in all, great work, good design, excellent animation, and clever criticism on today's gaming/videogames ''quality''(or lack thereof).
you are awesome, keep up the good work!
