Seventh Son:

Ben Barnes and Jeff Bridges as the apprentice and the master

It's Godzilla meets Transformers, shape shifting witches morphing into flying dragons. Which is as it should be in a fantasy/action flick. And it certainly helps that the most malevolent one, Mother Malkin, is played by Julianne Moore.

Chasing her down is Master Gregory, Jeff Bridges, acting like the grog in his flask is the real stuff. Either than or he thought he was in a comedy.

Master Gregory takes on a new apprentice, Tom, a seventh son of a seventh son. Luckily, Ben Barnes, who looks like a young Keanu Reeves, acts as if he's in Julianne Moore's movie.

The Movie Slut is not a connoisseur of fantasy flicks, but this one is fun, or would have been if Jeff Bridges wasn't playing it like The Dude in mephistophelian beard.
