This film's trailer and classification might lead you to believe it's a comedy and although it has some humor in it, it is primary a drama. I was expecting lots of laughs based on the trailer, but I realized the editing on the trailer doesn't match the type of editing style of the actual film.
The film is about two post-war veteran army rangers. Both have unresolved issues. One of the veterans is Army Ranger, Jackson Briggs (Channing Tatum). The second is a K-9 Army Ranger by the name of Lulu.
After Lulu's master death, Briggs is charged with the task of delivering the K-9 to its former master's funeral for a last goodbye. The two rangers are reluctantly paired together on a long road trip to the funeral. While on their journey there, the two eventually find comfort and solace in each other. But there are plenty of hiccups along the way.
The film doesn't spell out what Briggs and Lulu are going through. The story is carefully explained through the nuances in their acting and body language. So, this is a read between the lines type of movie. The film is a bit slow but that's probably a good thing considering what the intent of the film is meant to be. Briggs also has domestic issues, but the true nature of the issues aren't disclosed. But based on the fact he wants to leave on another rotation to active duty, it seems he is trying to escape problems with his daughter's mother. Can't tell if he is married to her or just a girlfriend.
It's a good film but probably not a film children will enjoy but empathic adults will understand. Particularly military families.
