I first heard about this movie in a radio interview, so I was aware that it was very low budget. But lately "sci fi" movies have been all about escalating action to the point of absurdity. Classic sci fi is about people reacting to new/mysterious/dangerous situations. This movie has that, with interesting protagonists. It has echos of Sin Nobre and El Norte, and yes, the context of "alien substitution" echoes District 9. But it's not a re-make, and it's consistently entertaining, with a straight-ahead narrative. There are only a few moments where a shock reaction is telegraphed. A big studio would have made this story into an effects extravaganza. But in my opinion it's more effective showing limited interaction with the aliens.
If you can handle real sci fi -- movies without the excesses of Transformers or 2012 -- this sci fi will satisfy.
