Variously,
Lucy,
Snowpiercer and
Ex Machina.
I was willing to suspend disbelief with Lucy, since I always like super powers being used to utterly demolish villains.
The
"you only use X% of your brain" myth was mildly annoying, since it is evidently such utter nonsense, and repeated often by people who either deliberately ignore reality, or who should probably attempt to use more than that percentage of their brains!
Snowpiercer was quite unusual, and Tilda Swinton looks the least like Tilda Swinton that I've ever seen her. It's a very novel approach to a post-apocalyptic world, although I would have preferred a slightly more complete ending. It seemed to be a little bit too open ended to suggest where things may go.
Ex Machina, as others have said, was thought provoking, even if most of the concepts weren't original. A movie which only had four characters of any significance was also novel, albeit that Kyoko is a relatively minor part. I was looking for hints about the British origins of the film, and the only obvious one was the ISO keyboard in the early shots, where you'd often see a US ANSI keyboard. Even though it was filmed in Norway, the helicopter had a USA registration, implying that they were trying to loosely imply an overall USA connection, especially with Corey Johnson being an actual US actor (cf Irish, Swedish, Japanese or Guatemalan!). Bluebook smacked of essentially being Google, which I guess was deliberate.
Oh, and even though it was quite a while back, Immortel (ad vitam) / Immortal was an interesting film, albeit very strange at times.
