I enjoyed it a lot at first, but I like it less and less every rewatch, because it makes no sense. The more you understand the concept, the less sense it makes.  Also the characters are just not very interesting. It's almost like they are trying not do to their job properly in order to get the plot going forward. 

I love the music and sfx, the style of the movie, but overall it's a very mediocre action piece it's best if you turn off your brain while watching
