When I saw the initial reviews, I immediately prepared for disappointment.
Turns out, the movie was great. Easily 7 to 7.5 and maybe a narrow 8/10 for me. It is technically above average, 3/10 is plain ridiculous.
I have to say this film is more drama than thriller.
And yes, it can use a bit of refinement on pacing, and does lack a bit of punch.
However, it did tug on my heartstrings on certain spots, and showcased a range of complex relationships and emotions between the characters.
It's great fun because in the end, its hard to tell who the villain is.
I say this as a person who appreciates Drama and slow tempo Art films.
This film is not meant to be:
1) a blockbuster thriller
2) a hard Sci Fi that pushes philosophical questions
Rather, it is more of a drama / tragedy that effectively uses the Sci Fi backdrop to highlight the contrasting character of the protagonist Leo. Who is a sensitive soul and a man pure at heart who is unaffected by all the neon signs and the madness that surrounds him.
