It is fairly obvious that this is a futuristic action movie starring Pamela Anderson. So if you buy this movie, you're probably a fan of either genre, hopefully both. If you're a Pamela fan, like me, then watching Pam watching paint dry will excite you. If you're a fan of futuristic action movies, like me, then Barb Wire wont be the best you'll see, but it's not bad either. Weaknesses that you might grumble about would be idealistic plots and cheesy storylines perhaps. If you really want to complain, you'll be disappointed by the lack of metaphor that this genre can sometimes powerfully convey. I can't answer for Dark Horse comic fans. If you are one, unlike me, then I suspect that you will also be disappointed, and that's fair enough.
However, Bar Wire has got guns, car chases, fast bikes (with guns), death-defying fight scenes, neo-nazi bad guys, plenty of characters, futuristic mind-reading machines, a twist in the tail, and of course Pam in and out of black leather, riding fast bikes and shooting guns.
So if you are a fan of futuristic actions movies AND a fan of Pamela, like me, this will be one of your favourite films. You'll know why: it's not for Kafka-esque portrayal of the human condition. There's no shame in liking simple gun fights, car chases, explosions and Pam. Admit this and free yourself. Sure, the opening scene of Pam blue-lit and being showered with water extends the opening plotline a little bit. If you don't like it, then perhaps you were a bit naive buying this movie.
If you've got a hang up about Pamela's talent or movies that lack depth, don't buy it. But let's face it, if you came across Barb Wire in your search results, you really should already know what you're getting. Don't skip it, watch it, and then watch Tank Girl too.
