Waste of time. Don't waste yours

The good bits:

• Filmed in Scotland, in Edinburgh;
• you get to hear the accent (and twinkle of Scots even).

The so-so bits:

• Yet another gruesome-serial-killer yarn. The "twist" isn't new either.
• Experienced actors (not just the two internationally known ones on the movie poster) earning their pay.

The bad: plot and direction

• a non-thrilling "thriller".
• There is no "aha moment", and even if you didn't the resolution coming miles away, it was lacking tension.
• and the actors seem not to have been directed much beyond saying their lines, so it's very uneven in acting quality.
• gruesome murder scenes and corpses without use. Some people may get their kicks from such...
