Sleep walking is new. Usually we see obsessive compulsive disorder, prosopagnosia, multiple personality, psychopath, sociopath or 'shut-ins' as psychological problems.
Nice drama. Lots of action and superb cinematography. Actors are great but not much chemistry between the two leads. As for storyline.. a bit draggy. I enjoy watching but definitely will not rewatch.
Special effects and CGI (especially with the transforming gun) - 7/10
Confusing level - 9/10
ughhhh...
