It's way premature for me to write any accurate or thorough review of this series, as I've only just now finished episode 4 of 8, but I wanted to put a word in about the cast as well as the dubbing.
The cast appears to do an excellent job, overall. There are a few misses, even a major one such as the leader of the Istanbul vampires, Dimitri, who is far too over-the-top and self-absorbed for my taste, but by-and-large this cast shines through convincingly.
The movie is filmed in their native Turkish language (forgive my ignorance; I have not researched what this language or dialect would be called), and subtitled. Additionally, someone decided to take the time and invest in the expense to have the entire scripts dialogue dubbed in English.
