Michael bay's 6 underground made on a budget of $150 million dollars is a boring, lifeless piece of mediocrity. The plot is straightforward a group of people (a billionaire, someone who can climb, someone whose mom doesn't love them and the rest) try to kill some bad guys. The bad guy himself is the most one dimensional villain, he just loves to be evil. The characters are dull and lifeless, you don't feel any attachment to them. The dialogue was dreadful and the flashbacks were hard to distinguish from the present. The action scenes were alright but there are countless films with better action. Ryan Reynolds was the only decent part of the film and even he wasn't too good. If you want action go watch James bond or John Wick not this average junk.
