kyrios I liked Alien 3 and Resurrection. They were far more entertaining than most of crap of today. I got all (5 + Prometheus) Aliens movies on DVD except Alien vs Predator ones, because I find them kind of ridiculous.
brent I can agree that Avatar wasn't that good on the plot side, but visually it was mindblowing. Now we are used to bombastic CGI, but back in 2009 in the cinema it blown my mind how beautiful the created world was and I've seen it in 3D then. Later when I watched a 3D movie I wasn't impressed. The colors, the depth were mindblowing. Even now on a huge 4K TV it looks great. And if you have oportunity to watch it on a UHD + 3D capable gear it's still impressive. And the plot... It's just Pocahontas in space. Nothing super-inteligent, but if you know other flicks by Cameron you know that his movies are more into visual experience than anything else.
