ENOUGH!!!!
Ok, I sick and tired of these type of movies. No sound effects, horrable diologe, zero originality, the batraying of characters... need I go on?
First thing first, get a mic, get some friends, get a decent peice of cloth (to hold in front of the mic as to help with recording quality, it's a real tip so as not to make this whole rant a complete waste) and do some voice work. While on the topic there are dosens of free sound effect all over the next and even some, unbeleivable as it sounds, from the game you got those sprites from.
Ok, next diologe, get some! Not every action or story must be explained by the characters. I highly suggest wtaching some Tarantino movies, they have EXELENT diologe. Also, stay true to the characters, Chrono (japanese spelling, bite me) was quite and lazy, but he had a good heart, voilence was not his thing but he was always willing to test himself. Anywho please try to reflect the traits of the original characters in your adaptions of them.
Originality, tough one, so far I've yet to see an original sprite movie that wasn't a complete parady or a hack n' slash. To be honest, I don't know if an original consept can be created from a console RPG. Games with little story are easy, but one with a rich and deep story can't be done, all anyone ever thinks about is the original plot. The only way I can see doing it is by doing something that could have taken place in the original story but wasn't covered in the game, kinda like most fanfics.
In closing, I'm dispointed in most sprite movies coming out of the portal (especially FFVI) because they all keep making the same, yet easily corrected, mistakes.
