Not a bad year for Sci-fi after all.
Guardians of the Galaxy was frigin' awesome.
I loved Edge of Tomorrow - I'm actually really sorry I didn't go see it in the theatres, because based on the trailers, it looked like another mindless action sci-fi with Tom Cruise but it turned out to be a really interesting story.
I've only recently seen the new Planet of the Apes and thought it was really good too, albeit the apes still looked too CGI.
And I think most comic book movies are sci-fi at their core (someone getting super-powers due to scientific experiments or genetic mutations is a very sci-fi concept) so I would count the new Captain America and the new X-Men among the really good sci-fi films of this year.
And then there's Interstellar of course - I didn't think it was all that amazing but there were some really good parts, plus it gave me an opportunity (possibly the last ever) to see a movie in IMAX 70mm (the Prague IMAX re-asembled their already decommissioned 70mm projector for it) and that was amazing!
