I love sci-fi, but if it's over the top like Men in Black, Armageddon, and many other films, I can get bored at times if I see too many ultra high budget films in a row. I liked the decidedly lower budget sci-fi movies (by Hollywood standards) like "The Invasion" and "Sector 9". CGI can be cool, but there is such thing as using too much CGI and having too many loud explosions that drown out the acting and dialogue. Also movies that have quiet moments use the concept of dynamics which I like vs. full-bore drama and action filling every second and every frame. What are your favorite Sci-Fi flicks?
