I gave a shot to The Shannara Chronicles because I knew it was some sort of fantasy story and that there was a cute girl in it (pictured). Being on MTV probably meant it’d be like, a CW show but with even lower budget and less talented (but still attractive) actors, but you never know?
But no, it doesn’t work. Fantasy dialogue is tough to pull off*. Prophecies and magic and elven lore and all that shit sounds ridiculous unless you’re a quality actor. And the main cast in this, at least based on the first 20 minutes I saw, they’re not up to it.
* – Science Fiction can be tough too, depending. Technobabble can be rough, but you can get around that with slang. Keanu Reeves in The Matrix worked fine because he was never asked to talk about reality simulation technology, artificial intelligence, direct neural interfaces, or any of that. Just “I know Kung Fu,” and that’s within his capabilities as an actor.
