This is Rambo in the desert with a Tuareg desert tribeman guy instead of stallones US commando . Mark harmon is just there because he is a good looking american he isn't well cast but he does an okay job except when he does alot of talking then you can't help but notice he isn't really right for the part. I loved the desert setting and the authentic details like the yawning camels and the salt lake with the sinkhole things. Lots of strategic, we'll wait here in this cave for a month subsisiting on this camels foot demonstrating our honor and persistence and then break into the place when the time is right kind of stuff.
Some will find it too guy movie-ish and tedious with all the gun battles and chasing, others will like it for this. Not exactly my favorite style but done well and authentic setting is a big plus and characters motivations and morals strike the right notes. how's that for a sloppy review?
Seriously, alot of celebrities have b movies they did early in their career but Mark Harmon shouldn't be embarassed about this because it kicks ass.
here is a good example of what I was talking about in the second sentence
