A disappointment. 'Mile 22' fails to deliver on what turns out to be a potentially interesting story. Mark Wahlberg's character is unlikable at times - the wristband thing with Silva was more annoying than meaningful. There's a lot of action which is somewhat entertaining but overall the characters don't really get developed.
Read the book when I was a teen, thought it was AWESOME. The movie though does not live to the expectations. The pace is too slow in the first part, and when things get interesting the movie is almost over. Great direction & character dev though. Having Arnie's POV = better IMO
