If you begin to watch a Troma offering, you know you're in for basically deliberately inept, silly (lazy? Never!) film making to the extent that it's 'so bad it's good' is expected, since because that is surely the intention of the Troma oeuvre, anyway:
So, if not to be another why waste ya time to watch, then first I would suggest you set it up as a fun billing along with others, not of the classic Arnold/ Sly more serious war is macho genre, but rather those of similar - but unintentionally so, though - dross of the likes of the S. Seagal and/or C. Connors entries into the genre.
Then as settling in for the inevitable ineptness, parts I found fun were the constant jewellery wearing air crash survivors (dangly spangly earrings especially) and the fact that the island army is surely made up of extras who were told to bring their own approximations of military outfit gear: the incongruities displayed are legion.
Of them, you can then also get a fine appreciation of the stunts people in executing their chops, be it jumping (mostly backwards) over objects (sandbags, oil drums, other 'dead' compatriots) or putting themselves in the correct position to plummet, 'shot and dead', from high places, trees especially: and, around the middle an amusing Arnold accent take rant in favour of the corrupt (US!) system
but then soon after a quite rather prescient almost 'conspiracist theory' the terrorist threat is really from inside from the system elite rejoinder from the hero (i.e well written scriptwriters): Then, throughout the interminable battles, there is a great wailing guitar background soundtrack to enjoy, too by which to get you finally to the end, at which point having so sat through such deliberate tosh, I would implore you wait around until the last end credit has rolled: it's a great denouement to the 'seriousness' of all that's gone before, making it, really, inarguably, surely one of Troma's best entries.
