This is a great theme.
If you want a high tech special effects film, with actors who look good but can't act, and no real philosophy to it, go for something more up to date.
If you want something that really speaks to the heart and to the spirit in man, with one of the single greatest actors of all time (Ed Harris, of "The Abyss" fame), without any fancy trimmings at all in the special effects department, go for this.
I loved it.
Like Harris's other classic, The Abyss, there is a powerful, positive message, about what is most important in life, shown clearly in this film. If you think that chivalry and knights in shining armour are dead and gone, but wish that they weren't, you'll love this.
