This is a decent movie by any metric. My only guess is fans of GOT or LOTR who expect CGI and huge battles... but aside from a few historical inaccuracies (like Vikings) this is a thoroughly enjoyable and entertaining romp into 13th Century Europe and I enjoyed it immensely. Especially the fighting versus the Mongols.
Leave pretentions aside and you'll enjoy this from start to finish. Fantastic scenery abounds and a decent plot entertains.
