There are awkward moments throughout the film. Much of it is anachronistic, almost embarrassingly so - the gang structures depicted in the film are pure 1950s; the clothing and hairstyles are late 1960s. the dialog is an off-setting mix of '50s and '60s. Within five years of the making of this film, most street gangs were becoming big business, thanks to the introduction of crack cocaine; in fact drugs are almost never used in this film, which is ridiculous. Finally, there's the music - nothing any gang member would be caught dead listening to, ever. The comic book/fantasy element simply doesn't justify or excuse these decisions, and they come off feeling like mistakes.
So we have an interesting reflection on an old Greek legend, a rapidly paced fantasy action film, and some unforgivable misfires in execution.
