This question tangentially speaks to my recent thread about scifi films that try to convey the unfathomable enormity of space and time.
I feel that I have outgrown the alien-of-the-week mentality. I am much more interested in the mysteries of outer space and the universe than I am seeing cowboy and Indian fights between space ships.
We are currently watching Gattaca, which was mentioned earlier in the thread, and totally digging it.
