Ignore the negative reviews
This film is not for everyone, but its heaps better than all the CGI spectacles, lame novel adaptions & mediocre rubbish that is coming out these days.
If you haven't seen it I recommend you check out the trailer; if you like it go buy the DVD because its a good movie.
There are some disturbing & uncomfortable moments; but in my opinion great films are meant to shake up the audience a bit, I want a film to have an impact on me because those are the films you remember.
I love the dark, eerie atmosphere of the film. Similar to David Lynch films there is a great mix of darkness, mystery, dreamlike imagery, comedy & the bizarre.
The cinematography is excellent, the use of music & sound is really well done, the acting is fantastic; Bill Pullman & the dodgy cops are particularly good.
I really like the film's ending & it leaves you wondering (or worrying) what the bad guys will get up to next. Give 'Surveillance' a chance.
