Or is it Jars? No wait that is not what they mean right? Either you are as cluelesss about war in general like I pretend to be or you may find my joke distasteful. Hopefully you can forgive me. The movie itself that has nothing much in common with the original Jarhead movie (which I have to rewatch, but I remember liking a lot), is closer to the 13 hours movie. For better or worse.
But I do like Scott Adkins and if you are here for some action (shooting, war scenario and whatnot), you could do worse. The stunts and the action are decently done to say the least. Not much story, not much in character development - but I don't think anyone expected anything in that department! No pun intended ... solid overall, if you have low expectations.
