O Guardião Invisível

First of all, The IMDb rating of 6.0 for this movie is complete nonsense . This is one of the best mystery movies in the serial killer genre I've seen . They have handled several complex subplots and back stories . This is not a slasher/ gore thriller ,so I guess people expecting blood splatters galore would be disappointed.

The main mystery and the central character have been treated excellently. There are however, a few loose ends and I felt the "monster/ guardian" subplot could have been skipped (or it's something which is part of cultural folklore which I didn't really understand). Overall ,an excellent mystery suspense movie with great atmosphere .
