Fist of all don't listen to the negative critics here this movie was made for TV and was the highest rated Mini-Series in 2 years for CBS (because it was good)Part 1 had 19.4 million viewers, Part 2 17 million. If you've seen some of these wackadoo Sci-Fi Channel movies this is not one of them. Area51 FX used a combination of actual stock footage blended with cgi and LightWave3D Modeling to create the FX with a budget close to $15 million. Keep in mind of just over a thousand reviews on IMDb 12.5% give this movie a 10 over on Amazon of 34 reviews it scores a 3.5 out of five. Not to shabby some people just like to pick fun movies apart as if this was meant to be Shakespearean its not its meant to be what it is a DISASTER MOVIE. Some movies with larger budgets have their flows to like 2012 which had a monster budget and awesome FX had a single family plot line while all heck breaks loose around the world same for DAY AFTER TOMORROW. This excellent TV-movie gives us several characters, some better than others and while I liked the other movies mentioned so much so that I bought them on Blu-Ray I just ordered the sequel CATEGORY 7 on Blu-Ray after watching this one on Sci-Fi channel over the weekend. Great fun, Very Good Special FX, some funny and interesting characters, likable acting and actors for me these days with some lame movies on TV this was a cut above 8 out of 10 stars for keeping me seated the full 3 hours.
