The Fall Guy should be renamed The Fail Guy.
The storyline is so weak it must have been dreamt up in the car by a screen write running late for a meeting with the studio, the characters are stereotypical, and the acting is mediocre (not that the actors had much to work with), and it completely fails to deliver any entertainment value.
As expected, it is filled with action, but these are stunts we have all seen a hundred times before. On the classic "fight on a truck" scene I had to go the washroom. Returning 10min later it was still going on.
In short, The Fall Guy is really boring and must be the least original movie of the year!
