First I'll say that this is an "adventure" movie in which action scenes are important, but here there's a sore lack of experience producing such scenes, which come out like soft, slow, unrehearsed fights- so this movie is doomed from the start. Add Eric Roberts' feeble attempt at a British accent and you have no hope of getting through it without fast-forwarding. The story itself is thin (and possibly objectionable in its portrayal of the local warriors), but I could see it working with the right cast and director.
