I've never read the books Shadowhunters is based on because, from what I've heard, Clare's novels are an egregious example of some of my least favorite YA tropes. Still, I started watching this series out of curiosity after reading some very funny posts about it. The first time I tried, I quit in the middle of the first episode. I thought the pacing was strange, the characters sounded like adults trying to mimic teenagers, and the fight scenes were choppy. Although I haven't gone back to rewatch the first episode, I was probably right about all of those things. However, when I was bored and gave it a second chance (starting near the end of the first episode), I enjoyed it a lot more. I think that once Clary is drawn into the shadow world it's easy to forget that she's a teenager, and the show really finds its footing in Clare's urban fantasy. I binged the rest of the show with no regrets, and I'm impatiently awaiting season 3B. This show won't be everyone's cup of tea, especially since I've heard it strays quite a bit from the source material, but I recommend it. Once it hit its stride, it kept me hooked the whole way through.
