The final film? well who knows but this isn't as bad as I've read and its certainly no worse than the fourth film ('Necropolis'). Basically the same plot lay out with the deadly toxic gas again being mistreated and lost, although this time its turned into a drug which was an interesting twist.
The story does follow on from the last film and has the same surviving cast members which is good but for some reason they don't seem to know what the gas is or what it can do as if the last film never happened. Yet this film does follow on from the last for sure as the characters all have the same names. I suppose they may not have seen the canisters in the last film but its still a bit odd, never the less the film plays out much the same as before with people going down one by one as we head towards the rave finale. The makeup is spot on just like the previous films and looks nice n slimy, nothing too new looking but it all works and does the job plus the classic 'Tarman' zombie (or another version) is back and looking sweet hehe.
I think this film also gets back to the humour aspect of the original two films which is good and in my opinion makes it worthwhile and a fitting addition to the series.
