This story of supernatural tree shaped men attacking a motley group of people in the middle ages has the look of a story with too many cooks spoiling the broth.
There were just too many characters who had superiority complexes, and the ones who would have the superiority complexes had the opposite.
The monks are depicted as ridiculous middle ages version of Frank Burns, and the other characters are just as one dimensional.
On the bright side, as contrived as it is, there is a bit of non contrived fates. A bit of "let the cards fall where they fall" look, instead of a deliberated goal appearance.
The biggest problem is "character". These characters all look like they were written by or for certain actors, which was probably the intention, but it looks too obvious. Way too many are too Hollywood, and few make sense for the era. For instance, the monks are depicted as cowardly weak mercenaries, when in fact the monks of the era could either be weak or mercenary, but couldn't be both.
There were too many Hollywood characters for the movie, too. Had it been a mini series, maybe it would work, although the characters were so standard and Hollywood that it would only work for the geekiest people.
More ridiculous was the woman who never ran out of arrows. I don't know where the arrows all were. They just appeared out of the air. I guess they dropped from the ceiling. Probably from an elaborate mechanism she devised that dropped three arrows every ten minutes.
