I only chose these two film out of the many sci-fi films, because these are the two that are on my mind, and there's a certain realism about both of them as compared to other sci-fi films in recent memory. I want to see Europa Report; not sure what it's about exactly, nor if it tries to stick to realism in any meaningful way, but it seems interesting. I love hard sci-fi, which is what I would consider the two above films.
What films in recent memory do you think could be added here? There's that Love film which I hadn't seen either, with Gunner Wright (Isaac Clarke). I don't know, what do you think? As for me, I have to just go the easy way and say I like Moon and Gravity equally. I just saw Gravity today (finally), and while there were a couple of things I didn't like, it was an overall fantastic experience to me.
