That's about all one can say for it. The main thing wrong with faith-based productions is that they of necessity involve the writer's interpretation of whatever faith (in this case Judeo-Christian) that they are peddling in their entertainment. But doing this leads to mixing up a lot of human traditions, myths, and downright errors. Dale Midkiff (formerly of good movies like Pet Semetary) spends a fair amount of time insisting they have to get their golden Christian Cross to Chichen-Itza. Nonsense. In the first place there are four temples at Chichen-Itza and he doesn't actually specify which one (at least not until after we've already arrived) and, of course, it is the largest. The Temple of Kukulkan---usually simply called "The Castle" because it is the largest and everybody knows it.
Add to this the legend that a bearded white man with supernatural powers named Kukulkan supposedly BUILT the thing and add to that the speculation by some Religious writers that this Kukulkan was really the Post-Resurrection Christ appearing to the Mayans to give them the good word because He said "Other Sheep I have which are not of this fold" to His disciples and because the Mayans are supposed to have been the lost tribes of the Israelites (or at least one or two of them) and a fun theory gets bandied about by all and some even begin to passionately BELIEVE all this even though there is no evidence for it.
The temple was built between 800 and 900 CE. Long before the Great Mayan vanished due to Climate Change (around the 10th Century CE and even longer before the lesser remnants of the Mayan people first encountered the Spanish *early 16th Century CE) so no Roman Catholic influence. Which in those days meant no CHRISTIAN influence. Did the Mayans reverence the cross as a sacred symbol? Yes. But not for the reason Christians do. ALL ancient peoples reverenced the cross, Notably because it represents the 4 directions, up, down, right, left. And the 4 compass points, North South, East, West. Also the four elements, Fire. Air, Earth. and Water.
One can go on with this.
But it does not have anything to do with any particular temple and there is no "temple cross" that does.
As for the Long Count Calendar. The Mayans didn't invent that. It was around long before their culture and empire arose. And every time it ended (which it had several times already) the Meso-Americans, and later "The Mayans" threw a grand party and started a new Long Count Calendar.
But if you don't mind the kind of goofy thinking that is essential to the plot of this thing then go ahead and watch it.
Hey! Dale Midkiff is in it!
