Underrated (spoilers)
Seventh Son may be compared to Jupiter Ascending as a delayed big budget, effects heavy, box office flop. But storywise it's more successful, featuring interesting characters in a somewhat revisionist fantasy tale.
Similarities:
Maleficent & Sleeping Beauty - witch's love spurned, transforms into dragon, anti-fairy/witch enemy
Hansel & Gretel: Witch Hunters - professional witch hunters, ogre helper, some witches are good
The Mortal Instruments - specialized monster hunters with mark
Solomon Kane - videogame-esque fight with boss demon
Eragon - order of warriors wiped out, Star Waresque in Medieval fantasy setting
Dragonheart - burnt out obsessed old warrior
The Black Cauldron - pig farmer boy
Revisions (mostly due to half witch):
Romeo & Juliet - witch-hunter & witch; but wait; they're both half-witches
Special chosen one squared - not just a seventh son, but a half-witch
Mother died fighting, not just hapless victim
