District 9...will there be a sequel?

Rating: 10/10 (16 August 2009)

I agree with another reviewer here that this is one of the 5 best films of the year so far....I even agree with his other 4 choices!.....Not only is the writing and plot a bit more sophisticated than your typical science fiction film, but the special effects are seamless....The prawns actually do look real and interacting with the human actors.
Now, I wonder if the whole movie was a set up for a sequel 3 years from now? I'll be there! But as my friend commented, what could the sequel possibly be about? Would it take an "aliens revenge" approach...or could they show us how to live properly via their advanced technology? I'd be curious to hear what the rest of you have to say about this. Thanks!
