Lots of judgment, yep.
Haven't seen it but seen enough of the plot summary and the plot to suggest i would be watching some kind of fantasy movie.
Why not make a movie about a handful of farmers fighting 300 Spartans or Roman Legions and see what happens?
Providing of course it comes out of that Fantasy land called Hollywood.
But then that wouldn't sell would it, since you know, it doesn't have bad Germans in it.
If you are going to create this kind of tripe at least make it half believable.
In before: yea but there were feats of heroism on both sides where combatants who were vastly outnumbered scored some victories.
