I'm not going to be too harsh judging this movie because this wasn't supposed to be a movie.

This was originally produced as the pilot episode for a Saint reboot series in December 2012. Roger Moore (the original Saint from the 60s) was to be the producer of the new series and Adam Rayner was to star as Simon Templar with Eliza Dushku as his girlfriend Patricia Holm. The reboot series never saw the light of day. The pilot was redone to become this movie.

IMO none of the attempted reboots since the original Roger Moore series have stayed true to the original Simon Templar character. I don't know why they diverted from Leslie Charteris' original character arc and themes. That was a mistake. I'm watching the original series (it's in Black & White for the first 4 seasons) and it's very good and has its own brand.
