Bwahahaha

I think the reviewer must be rating on a b-movie scale. I don't believe anybody in their right mind would rate this a 7 out of 10 when comparing it to movies that you could actually consider "good" - but I know I've reviewed b-movies where I gave them a high rating based on what I've seen in other low budget films.

A movie like this I find enjoyable because of how ridiculous the effects are, how wooden the acting is, and how goofy the plot elements are. They add up to be a quite enjoyable (though quite cheesy) view. I've seen tons of b-movies and some of them have a tendency to drag on and put me to sleep. A film like this is actually fun to watch - hence why a reviewer might give it what seems like an outrageously high rating.

So yeah... obviously on a scale from 1 to 10 where a film like Citizen Kane or Goodfellas (or whatever) is near the top this film would have to be near the bottom. But in terms of b-movies I would definitely give this at least a 6.
