This movie was awesomely bad [spoilers, duh]
I've watched all three Librarians and they've all been awesomely bad. Cheese-tastic, even. But still entertaining, which is a good thing.
This one had its moments, notably the dust-fight between the big bad and the good girl, the opening sword fight, and some of Flynn's dialogue, but mainly it's awesome because it revels in its own badness.
I hope TNT keeps making these. Seriously.
