48 hours is more than enough time to bang out a decent little 4 minute film, but the fact that you played hooky half way through your production to go to a concert kind of speaks volumes as to how serious you took all of this. Why you didn't just knuckle down, and pull off something really unique and clever, and chilling.... is beyond me.
I think that when you are doing a short film like this, you need to throw the audience into a very dramatic situation right from the first shot - and having a woman in her kitchen hitting meat and then clubbing some nice guy at the door doesn't cut it cuz frankly.... it's not interesting and comes off as terribly formulaic and dull. I mean, had the guy at the door been unable to speak a single word before the woman just went ballistic on him, pulverizing him with the mallet (juxtapostioning those hits with the mallet hitting the meat on the table would have been cute)... THAT would've been more attention getting.
For a short film, the audience needs to be put in a more challenging situation; a predicament that really takes them by surprise, and gets them involved. A guy waking up tied to a table is just about as cliched as someone waking up in a sweat and realizing they were "just dreaming." You need to be more clever than that. This isn't the 70s anymore.
Having said that, I didn't get the story, the point there of, the punch line etc. Did I miss something?
As for tech feedback.... Well thought out lighting set ups would have added mood and ambiance, a more suitably creepy room likewise, and more thought put into the framing of your shots was definitely something that could have been done.
The older woman was passable in her role, but the other two were just grating on the ears; the young girl especially so.
My two schillings.
