I must admit it has been sometime since the Boston Marathon bombing and I honestly couldn't remember all that happened on that awful day.

It's a good film that actually mixes real events and comments with the cast and certainly keeps you on your seat until the conclusion of the film.

Didn't want to say too much as I know I would only spoil it for you guys who want to watch the movie.

Mark Wahlberg plays the part of a police officer very well and is constantly up and down with his emotions during the film.

The film is very exciting and ruthless at times but is very close the facts of this awful event and really tests your memory to see how much of the original incident.

Peter Berg brings an account of the Boston Marathon bombing of 2013. Three people died over 200 were injured as two bombs went off near the finish line. Bombs placed by the Tsarnaev brothers who were of Chechen origin.

Once the bombs go off, Patriots Day becomes a procedural thriller. It focuses on the down on his luck with a bad leg, fictional hero Sergeant Tommy Saunders (Mark Wahlberg.)

As the film progresses the most interesting and intriguing character is Special Agent Richard DesLauriers (Kevin Bacon) the FBI agent in charge of the investigation. Berg deserves credit for having a nuanced portrayal of the FBI in this film. It is just a shame that DesLauriers is relegated to the background. It would had been a different film with him as the lead but a better one.

Some of the characters appear who seemed to be unrelated to the movie's narrative until much later on. An example is the Chinese student Dun Meng who has a frightening encounter with the brothers late at night or Sergeant Jeffrey Pugliese (J K Simmons) the cop in Watertown.

The film is uncertain about its treatment of the Tsarnaev brothers. Were they hardened criminals, committed terrorists or just two idiots who could not even get the right type of milk for a baby? At times the brothers appeared to be dim, glad that they were driving a Mercedes.

The heroes of Patriot's Day are the people of Boston and the victims. However there is something both glib and empty about this movie using a real life tragedy for a commercial thriller so soon after the events.
