Enjoyment of this film is all about expectations. If you're expecting a serious war movie or deep examination of the heart of a warrior, you will be sadly disappointed. If you're expecting an all out Saturday-morning cartoon brought too life, you will be pleasantly surprised. The plot almost holds together. The production values and acting don't get in the way. Most of the CGI and effects work. The action is non-stop.
There are some plot holes. Why are they transporting such a small case over land, when it would be safer and quicker to take it by air? Why does the President of the United States have a British accent? Why is the Joe base virtually uninhabited when the warheads are being stolen, when it was populated by hundreds of 'Joes' just a few hours earlier?
Luckily for the producers, all of that is relatively easy to overlook. This movie is not the clinker that some comic/cartoon translations turn into. It's pretty fun.
