I seem to be one of the few, that didn't really like Interstellar. Red Letter Media's review reflects my thoughts very precisely (though, they did like it and do recommend it).
in my eyes Interstellar is too much of an homage, so much that the movie itself gets lost in dozens of throwbacks to other, better, sci-fi movies (2001 being the obvious elephant in the room, but also Contact, Event Horizon etc.)
I'll give it a second look when the inevitable Director's Cut version comes out, but for now I can't say I enjoyed it
