Fell short in every way possible. I've been a longtime TMI fan and was highly anticipating this series. What a slap in the face this has been. The acting was terrible, the characters (while they fit decently with their descriptions, somewhat) were so under developed it hurt my soul, the fight scenes were very obviously choreographed, there were so many changes made that literally made no sense. If you are a fan of the books, steer clear of this abomination.
(The only reason I gave it a 1 star is because the graphics were "alright"...)
----- Update (3 years later...)
I went back, I watched it all, somehow I fell in love with the characters, their stories, their relationships, and now I'm legit heart broken and I miss Magnus. What has happened to me.
I started "watching" this because I needed some background noise while cross stitching lol, once season 2 kicked in, it was obvious a lot has changed (whether it was taken on by someone new, I have no idea, never bothered to look it up). It interested me enough that I stopped cross stitching and actually wanted to put it on to watch. *shrug*
