Just finished watching the series. In all I really liked it, big fan of these types of series. Closest I can come up with is Kingdom, except that one had an incredibly kickass main character. Battles are way more drawn out there, and of course the whole CGI issue. Still think of Kingdom as quite superior.
Anyways, nothing in the series really bothered me all that much particularly considering all the complaints I saw throughout the thread. I was fairly indifferent to Arslan as the main character and lack of female characters a bit of an issue as well, but that's fairly standard in these types of medieval war shows. I would've liked to see the Queen more though, she was forgotten after the first handful of episodes which was a shame. She seemed to have an interesting story to tell and thought she would have some political machinations to be shown throughout.
Maybe that's for the second series.
The other complaint is that I thought we would see Arslan continuing his training during his journey. Other than a scene towards the end of the series, none of his camp figured to keep training him. Which is disappointing, since I thought that was Farangis' main mission after all, to teach him martial arts and what not. Would've been a bit cool to see Arlan also learning to communicate with the Djinn, in part it might play a role against those sorcerers.
But, I was thoroughly entertained by it, will look forward to the next one which starts in July.
