This movie is seriously missold. Having seen the trailers I expected a good old fashioned whodunnit murder mystery.

Imagine my surprise that when the characters are first interviewed the film actually shows the true version of events. It's quite funny as one story contradicts another and the over the top characters throw digs at one another. This mechanic is also used when the murderer is interviewed... So yes, the murderer is know within the first 20 minutes of the film. The film also uses a plot device where one character cant lie without throwing up. It makes the investigation farcical when the detective has a 100% accurate witness statement. He may as well have had CCTV.

So the investigation you already know the ending to, you're not rooting for the murderer to get away with it (which is what the film is really about) and the rest of the characters are made to be dislikable so you're not rooting for them either. So in a 90 minute film you have zero interest in the middle 70 minutes, it is incredibly boring.

The final 10 minutes has a few twists that are truly ridiculous and I'd long ago lost interest.
