I did an Alien weekend. First we watched District 9 on blu-ray, and tonight Avatar in 3D Imax. District 9 wins IMHO. Both great movies, and yes Avatar had some great visual effect, but the story was way to "meh" for me. District 9 is definitely a movie I am going to own, and cannot wait for a sequel. Hopefully it does not take "3 years" (hehe).
