Fatally-Yours has published a very positive review of “The Bet.” An excerpt:

The mood of the film is immediately set by the low lighting and dark, grimy look of the film. The foreboding atmosphere is intensified by the eerie and punctuated score… The mysterious hallway and its two gambling inhabitants, flashes of the woman’s past and the ending all point to a far “bigger picture” perspective. Though the film’s fantastic ending is open for interpretation, it contains a supernatural element that led me to believe the two men were much greater and more important than they first seemed. They hold the key to people’s fates and gamble with human souls. I will leave it at that, because I don’t want to give too much away, but it has an ending that left me awestruck.
