It's funny how the actor called Finn does not play the part of Finn in this film. :P
All kidding aside, this was a highly addictive film that surprised me a lot. When I jumped in I expected a bad plot based on outrages decision making and nonsense. And even though there are still points of critique in that matter left, overall this does not affect the film in a way it aggravates the viewer.
The plot setup is basic but not clichéd, and from there on it uses every scene carefully to set up a plot with some unexpected twists. You can see the creators jumped in this project and seemingly were dedicated to what they were creating. Since (almost) every scene has it's value and is worked out very detailed (IMDB only has 1 goof on the movie so far. Yes it is an indie movie, so it won't have as much engagement as others, but still.)
Any plot that has to do with time travel and the like is hard to set up without having paradoxes, and there are few films who manage to handle them correctly. This one isn't perfect, but it does a nice job in keeping them very limited.

The first thing that got me thrilled was the music used in the movie. I am already a big fan of electronic music, but it is hard to use in film since it is more often than not disruptive in its presence. Not here, it balances some hard-trance scenes with more subtle spheric suspension building sounds. It backs the claustrophobic experience of the small set, and magnifies the surrealism of science fiction in a sublime way.
As the film progresses you get sucked in more and more into the story, especially after the 2nd act where the character development of the main persona is getting really interesting. This 3rd part of the film is by far the best part, with the biggest twists and captivating ordeals the characters have to face. I won't say much about the ending to prevent spoilers, but it left me hungry for a sequel, which will most likely never come. I am still not sure if that feeling was a good or bad thing.

I will be rating it at a 7(+) for now, but I am going to watch it a second time, because it is definitely worth it.
