District 9

I'm glad the early marketing kept most of the plotline obscured, and just set up the premise where aliens have shown up on Earth, and their space ship floats high about the ground, and they basically are quarantined in District 9 from the general population that grows weary of their presence as years pass.

The visual effects are really well done when it came to the aliens and how they looked in broad daylight, co-habitating with us on Earth.  There is a nice thread of dark humor that underscores some of the violence, but the film does make use of its R rating when needed. I was struck by how reminiscent some of the beats were when compared to Robocop in spots, but homage or not, used well in service of the story.

Given all the special effects, the acting never takes you out of the scenes when the aliens are also in the scenes, so a solid effort by the main lead acting performance by Sharlto Copley, as well as some of the main alien characters, a father and son tandem.  The direction by Neill Blomkamop is efficient and serves the story well.

Don't want to say much more, but if you're on the fence or intrigued by the trailer or ads, I'd suggest seeing it on the big screen, it's got plenty of story and action, as well as sci-fi and social allegories on display (though not unbearably so).

I give it 3 stars or  a grade of B (visual effects get a B+).
