The End's Beginning, first episode of The Witcher, give to us a good introduction to his world. I didn't played any of the three Witcher games, but I want to, neither have read the books, that I will certainly buy, so the only thing I did know abou The Witcher was some characters names and what this is about. I know there is more to be shown but this first episode did a good job introducing it all. Henry Cavill is cool, I don't know much abou Geralt so I don't know if he is 'faithful' to the books and/or games, or if he does justice to Geralt's characters, but his acting is pretty good, I didn't connect to Geralt, but there's more seven episodes and I know they will develop him more through the season. All the other actors are good as well. About the characters, I know Ciri is gonna be a big part of this so I expect to care about her as well.
The CGI is good, the monster at the beginnning of the episode, a Kikimore, is well done. All the costumes are great, loved them all, gives the classic fantasy book feeling, but it's all something fresh somehow. The coreography is also great, loved the battle between Geralt and Renfri's men is really, really good, and violent as well, and being without cuts is what made it better, even not being something new, as in Daredevil, made by Netflix as well. The directing of Alik Sakharov, that directed episodes of Game of Thrones, is good, the pacing is great here, it was indeed a great start for this series.
