I'll never fully understand exactly how people rate films here; try as I might, the reasoning eludes me...
Anyway, DEFINITELY better than it's current 4.4 rating (especially if graded on the curve with so many other garbage films out there) Well written and acted; especially well directed. Very engaging and suspenseful. YES, we've seen this kind of thing before and NO, it's not the absolutely most original story out there, BUT, a well done film is a well done film, and that is SUPPOSEDLY why we rate and review films here, right...?
The primary actor does an excellent job as the calm 'Cleaner' Cole. There is very nice use of photography and editing and excellent use of sound design to add to the strong psychological mood of the film (with the very minor exception of unfortunately one of my personal neurotic irritations where pouring drinks and other consequential sounds are SO bloody loud, MUCH louder than they should be - GOD I hate that!)
So, if you like solid, competent, Psychological thrillers either with or without 'Twists' and as long as you appreciate good film making, then you should definitely enjoy this movie. BTW, that was the first time I've ever seen Oz Perkins (Anthony's son) who also co-wrote the excellent screenplay, and I felt that he carried the 'disturbed' torch well where his father left off. I would LOVE to see him do more Horror films, but he hasn't really done very many at all.
Overall the movie is strong on mood if a bit lighter on substance. Not anything earth-shaking, but a decent, well done, enjoyable Thriller...
