Sound design is an art all it's own, and the people who are really good at it are well paid... it's not surprising you wouldn't necessarily consider many aspects of it because a) you're not one of those full time sound design people, and b) you're probably like (sadly) most of the low/no-budget filmmakers and wouldn't ordinarily give anywhere near the attention that's given to the cool camera moves, etc, to the audio.
It's the sad truth of things.. most low & no budget film makers are more concerned about trying to achieve a particular look than capturing and mixing good audio, when ideally if it were the other way around there would be a much larger portion of these films that was actually enjoyable to watch.
Wow, I'm ranty tonight.. hehe
