Alright. Before I get into the point of this post. I’m going to say that I am a fan of the books. I read all of them. Have read the Bane Chronicles, The Infernal Devices, Shadowhunter Academy... everything that is related to this Shadowhunter world. I love them.
Now. I have seen TMI fans complaining left and right about the show...we have KNOWN since they announced the show that it was going to have differences. Most TV adaptions do. They do it on purpose most of the time to make the experience fresh and new for EVERYONE.
I have never been disappointed by a TV adaption I have watched because every single one of them are Alternate Universes. (Except Eragon...that sucked. No offense.)
Another thing I have seen people complaining about is the acting. It is a bit over the top and campy. No denying it. Thing is...most low budget new television shows are to begin with. Usually about 5 or 6 episodes in, the acting normalizes as the actors and actresses fall into their roles more comfortably and become more accustomed to the pace of the show and the world it exists in. Sometimes it takes up to half a season to stabilize.
The CGI... All I need to say is, it’s low budget. If the show becomes successful that will change. They will have more money for better effects.
These things being said, give it a chance. It only JUST started guys.
