As far as TV movies go i thought this was really good. I've seen it twice and wouldn't mind a third viewing. Although it is historically flawed did not matter to me. I view this as more of a fantasy movie than being a historical account. I don't believe it was meant to be taken seriously as a true account of Polo's stories (which many are doubtful or stretched themselves).
The acting throughout the picture, for the most part, is surprisingly good and well executed. The set designs and backdrops are excellent and quite colorful. I won't get into the fact that the costumes are also historically inaccurate, i could care less truthfully.
Check it out, you may just like it...just don't expect Polo's real life adventures (fantasies?) on the screen.
