Chris Roberts shouldn't be blamed fully for this movie's awfulness.
I don't think it's completely horrible, I gave it a 6, and that's an honest rating from me.
I think this is one of those movies that suffers from ballot-stuffing on this site, just like nearly every other movie on here.
Anyway, I think these things would have made this movie worthwhile:
Bigger budget.
If Chris Roberts would have written the screenplay.
And I thought all of the actors/actresses did okay. I think the best ones were definitely Jürgen Prochnow, David Warner, and Tchéky Karyo.
