Plotwise, it's a run-of-the-mill monster horror flick. The camera takes its time. There's a few interesting shots, but mostly there's a lot of looking at actors who are bing given direction along the lines of "just like that, only a little bit less subtle with your emotions this time." Throw in the post-Vietnam banana republic focus on jungle warfare and big guns for a little bit of spice.
We also get lots of time with Arnold with his shirt off and he even makes an arrow with gunpowder and then fires it what appears to be 3 feet in one shot but is actually 60 feet because of movie magic. Of course he saves the day and even gets to leap aside from a nuclear explosion at the end. There's almost enough camp to sustain it, but not really.
Oh well. All's well that ends Ahnold.
