Seems there is a question of stereotypes and race in your short here, Pedro.  I decided to check it out and form my own opinion.

My first opinion is that you are using too many exclamation points!!!

"Thief 1 grabs a paper from his pocket!", you tell us at one point.  "The lights are turned off!", at another.  I would tone that down to start.  Use them sparingly, or it gets kind of silly.

I found this story amusing.  I actually liked the ninja and his stupid accent.  As if ninjas actually rob houses haha.  It's kind of absurd.

The only problem I had with the treatment of race here was that it was too superficial -- simply tossing the word "nigga" around is not digging very deep.

Is there a point you really want to make about race with this piece?  Think about that question for a moment.  Dig for it.  If there is, then have these characters say something meaningful towards that end.  It can still be funny, but also carry a little weight at the same time.

If you are simply playing the races off each other for laughs -- then yeah, you should abandon that angle and stick with the union discussion -- which is also a pretty funny idea.  My opinion, anyway.

About unions, I think you would take a look at  Elia Kazan's "On the Waterfront" or  Danny DeVito's "Hoffa" They can be usefull in order to be inspired by.

This is my two nickels, amigo

alright, will check it Helio!

Also Bert thanks for the advice.

It's true I kind of abused the word "nigga", I agree with that, but it was to build it up to the last 'white nigga' joke.

But you are right, a little superficial.

Busy with the rewrite.

I think I'll make two drafts, one that will have the 5 minute limit. And a longer one where i will develop the characters even further.

hello, i wrote a short like this a few years back where a male and female thief break into the same house and they decide to settle it over a game of monopoly.
liked the dialogue in yours but the characters were a bit stereotyped
good luck

thanks for your comment accouristine!
